 *
 * This register represents a 16-bit free running counter that can be read and
 * written by the CPU. The timer starts from 0x0 after Reset, counts linearly to
 * 0xFFFF, and wraps around. The timer is clocked by the FlexCAN bit-clock, which
 * defines the baud rate on the CAN bus. During a message transmission/reception,
 * it increments by one for each bit that is received or transmitted. When there
 * is no message on the bus, it counts using the previously programmed baud
 * rate. The timer is not incremented during Disable , Stop, and Freeze modes. The
 * timer value is captured when the second bit of the identifier field of any frame
 * is on the CAN bus. This captured value is written into the Time Stamp entry
 * in a message buffer after a successful reception or transmission of a message.
 * If bit CTRL1[TSYN] is asserted, the Timer is reset whenever a message is
 * received in the first available Mailbox, according to CTRL2[RFFN] setting. The CPU
 * can write to this register anytime. However, if the write occurs at the same
 * time that the Timer is being reset by a reception in the first Mailbox, then
 * the write value is discarded. Reading this register affects the Mailbox
 * Unlocking procedure; see Section "Mailbox Lock Mechanism".

 * HW_CAN_ECR - Error Counter
 ******************************************************************************/

/*!
 * @brief HW_CAN_ECR - Error Counter (RW)
 *
 * Reset value: 0x00000000U
 *
 * This register has two 8-bit fields reflecting the value of two FlexCAN error
 * counters: Transmit Error Counter (TXERRCNT field) and Receive Error Counter
 * (RXERRCNT field). The rules for increasing and decreasing these counters are
 * described in the CAN protocol and are completely implemented in the FlexCAN
 * module. Both counters are read-only except in Freeze mode, where they can be
 * written by the CPU. FlexCAN responds to any bus state as described in the protocol,
 * for example, transmit Error Active or Error Passive flag, delay its
 * transmission start time (Error Passive) and avoid any influence on the bus when in Bus
 * Off state. The following are the basic rules for FlexCAN bus state transitions:
 * If the value of TXERRCNT or RXERRCNT increases to be greater than or equal to
 * 128, the FLTCONF field in the Error and Status Register is updated to reflect
 * 'Error Passive' state. If the FlexCAN state is 'Error Passive', and either
 * TXERRCNT or RXERRCNT decrements to a value less than or equal to 127 while the
 * other already satisfies this condition, the FLTCONF field in the Error and
 * Status Register is updated to reflect 'Error Active' state. If the value of
 * TXERRCNT increases to be greater than 255, the FLTCONF field in the Error and Status
 * Register is updated to reflect 'Bus Off' state, and an interrupt may be
 * issued. The value of TXERRCNT is then reset to zero. If FlexCAN is in 'Bus Off'
 * state, then TXERRCNT is cascaded together with another internal counter to count
 * the 128th occurrences of 11 consecutive recessive bits on the bus. Hence,
 * TXERRCNT is reset to zero and counts in a manner where the internal counter counts
 * 11 such bits and then wraps around while incrementing the TXERRCNT. When
 * TXERRCNT reaches the value of 128, the FLTCONF field in the Error and Status
 * Register is updated to be 'Error Active' and both error counters are reset to zero.
 * At any instance of dominant bit following a stream of less than 11
 * consecutive recessive bits, the internal counter resets itself to zero without affecting
 * the TXERRCNT value. If during system start-up, only one node is operating,
 * then its TXERRCNT increases in each message it is trying to transmit, as a
 * result of acknowledge errors (indicated by the ACKERR bit in the Error and Status
 * Register). After the transition to 'Error Passive' state, the TXERRCNT does not
 * increment anymore by acknowledge errors. Therefore the device never goes to
 * the 'Bus Off' state. If the RXERRCNT increases to a value greater than 127, it
 * is not incremented further, even if more errors are detected while being a
 * receiver. At the next successful message reception, the counter is set to a value
 * between 119 and 127 to resume to 'Error Active' state.

 *
 * Reset value: 0x00000000U
 *
 * This register defines the flags for the 32 Message Buffer interrupts for MB31
 * to MB0. It contains one interrupt flag bit per buffer. Each successful
 * transmission or reception sets the corresponding IFLAG1 bit. If the corresponding
 * IMASK1 bit is set, an interrupt will be generated. The interrupt flag must be
 * cleared by writing 1 to it. Writing 0 has no effect. The BUF7I to BUF5I flags
 * are also used to represent FIFO interrupts when the Rx FIFO is enabled. When the
 * bit MCR[RFEN] is set, the function of the 8 least significant interrupt flags
 * BUF[7:0]I changes: BUF7I, BUF6I and BUF5I indicate operating conditions of
 * the FIFO, and the BUF4TO0I field is reserved. Before enabling the RFEN, the CPU
 * must service the IFLAG bits asserted in the Rx FIFO region; see Section "Rx
 * FIFO". Otherwise, these IFLAG bits will mistakenly show the related MBs now
 * belonging to FIFO as having contents to be serviced. When the RFEN bit is negated,
 * the FIFO flags must be cleared. The same care must be taken when an RFFN
 * value is selected extending Rx FIFO filters beyond MB7. For example, when RFFN is
 * 0x8, the MB0-23 range is occupied by Rx FIFO filters and related IFLAG bits
 * must be cleared. Before updating MCR[MAXMB] field, CPU must service the IFLAG1
 * bits whose MB value is greater than the MCR[MAXMB] to be updated; otherwise,
 * they will remain set and be inconsistent with the number of MBs available.

 * @name Register CAN_CTRL2, field TASD[23:19] (RW)
 *
 * This 5-bit field indicates how many CAN bits the Tx arbitration process start
 * point can be delayed from the first bit of CRC field on CAN bus. This field
 * can be written only in Freeze mode because it is blocked by hardware in other
 * modes. This field is useful to optimize the transmit performance based on
 * factors such as: peripheral/serial clock ratio, CAN bit timing and number of MBs.
 * The duration of an arbitration process, in terms of CAN bits, is directly
 * proportional to the number of available MBs and CAN baud rate and inversely
 * proportional to the peripheral clock frequency. The optimal arbitration timing is
 * that in which the last MB is scanned right before the first bit of the
 * Intermission field of a CAN frame. Therefore, if there are few MBs and the system/serial
 * clock ratio is high and the CAN baud rate is low then the arbitration can be
 * delayed and vice-versa. If TASD is 0 then the arbitration start is not
 * delayed, thus the CPU has less time to configure a Tx MB for the next arbitration,
 * but more time is reserved for arbitration. On the other hand, if TASD is 24 then
 * the CPU can configure a Tx MB later and less time is reserved for
 * arbitration. If too little time is reserved for arbitration the FlexCAN may be not able
 * to find winner MBs in time to compete with other nodes for the CAN bus. If the
 * arbitration ends too much time before the first bit of Intermission field then
 * there is a chance that the CPU reconfigures some Tx MBs and the winner MB is
 * not the best to be transmitted. The optimal configuration for TASD can be
 * calculated as: TASD = 25 - {f CANCLK * [MAXMB + 3 - (RFEN * 8) - (RFEN * RFFN *
 * 2)] * 2} / {f SYS * [1+(PSEG1+1)+(PSEG2+1)+(PROPSEG+1)] * (PRESDIV+1)} where: f
 * CANCLK is the Protocol Engine (PE) Clock (see section "Protocol Timing"), in
 * Hz f SYS is the peripheral clock, in Hz MAXMB is the value in CTRL1[MAXMB]
 * field RFEN is the value in CTRL1[RFEN] bit RFFN is the value in CTRL2[RFFN] field
 * PSEG1 is the value in CTRL1[PSEG1] field PSEG2 is the value in CTRL1[PSEG2]

 * @brief HW_CAN_RXIMRn - Rx Individual Mask Registers (RW)
 *
 * Reset value: 0x00000000U
 *
 * These registers are located in RAM. RXIMR are used as acceptance masks for ID
 * filtering in Rx MBs and the Rx FIFO. If the Rx FIFO is not enabled, one mask
 * register is provided for each available Mailbox, providing ID masking
 * capability on a per Mailbox basis. When the Rx FIFO is enabled (MCR[RFEN] bit is
 * asserted), up to 32 Rx Individual Mask Registers can apply to the Rx FIFO ID Filter
 * Table elements on a one-to-one correspondence depending on the setting of
 * CTRL2[RFFN]. RXIMR can only be written by the CPU while the module is in Freeze
 * mode; otherwise, they are blocked by hardware. The Individual Rx Mask Registers
 * are not affected by reset and must be explicitly initialized prior to any
 * reception.
