Kojto | 90:cb3d968589d8 | 1239 | * 0xFFFF, and wraps around. The timer is clocked by the FlexCAN bit-clock, which |

Kojto | 90:cb3d968589d8 | 1241 | * it increments by one for each bit that is received or transmitted. When there |

Kojto | 90:cb3d968589d8 | 1525 | * This register has two 8-bit fields reflecting the value of two FlexCAN error |
Kojto | 90:cb3d968589d8 | 1526 | * counters: Transmit Error Counter (TXERRCNT field) and Receive Error Counter |
Kojto | 90:cb3d968589d8 | 1527 | * (RXERRCNT field). The rules for increasing and decreasing these counters are |
Kojto | 90:cb3d968589d8 | 1528 | * described in the CAN protocol and are completely implemented in the FlexCAN |
Kojto | 90:cb3d968589d8 | 1529 | * module. Both counters are read-only except in Freeze mode, where they can be |
Kojto | 90:cb3d968589d8 | 1530 | * written by the CPU. FlexCAN responds to any bus state as described in the protocol, |
Kojto | 90:cb3d968589d8 | 1531 | * for example, transmit Error Active or Error Passive flag, delay its |
Kojto | 90:cb3d968589d8 | 1532 | * transmission start time (Error Passive) and avoid any influence on the bus when in Bus |
Kojto | 90:cb3d968589d8 | 1533 | * Off state. The following are the basic rules for FlexCAN bus state transitions: |
Kojto | 90:cb3d968589d8 | 1534 | * If the value of TXERRCNT or RXERRCNT increases to be greater than or equal to |
Kojto | 90:cb3d968589d8 | 1535 | * 128, the FLTCONF field in the Error and Status Register is updated to reflect |
Kojto | 90:cb3d968589d8 | 1536 | * 'Error Passive' state. If the FlexCAN state is 'Error Passive', and either |
Kojto | 90:cb3d968589d8 | 1537 | * TXERRCNT or RXERRCNT decrements to a value less than or equal to 127 while the |
Kojto | 90:cb3d968589d8 | 1538 | * other already satisfies this condition, the FLTCONF field in the Error and |
Kojto | 90:cb3d968589d8 | 1539 | * Status Register is updated to reflect 'Error Active' state. If the value of |
Kojto | 90:cb3d968589d8 | 1540 | * TXERRCNT increases to be greater than 255, the FLTCONF field in the Error and Status |
Kojto | 90:cb3d968589d8 | 1541 | * Register is updated to reflect 'Bus Off' state, and an interrupt may be |
Kojto | 90:cb3d968589d8 | 1542 | * issued. The value of TXERRCNT is then reset to zero. If FlexCAN is in 'Bus Off' |
Kojto | 90:cb3d968589d8 | 1543 | * state, then TXERRCNT is cascaded together with another internal counter to count |
Kojto | 90:cb3d968589d8 | 1544 | * the 128th occurrences of 11 consecutive recessive bits on the bus. Hence, |
Kojto | 90:cb3d968589d8 | 1545 | * TXERRCNT is reset to zero and counts in a manner where the internal counter counts |
Kojto | 90:cb3d968589d8 | 1546 | * 11 such bits and then wraps around while incrementing the TXERRCNT. When |
Kojto | 90:cb3d968589d8 | 1547 | * TXERRCNT reaches the value of 128, the FLTCONF field in the Error and Status |
Kojto | 90:cb3d968589d8 | 1548 | * Register is updated to be 'Error Active' and both error counters are reset to zero. |
Kojto | 90:cb3d968589d8 | 1549 | * At any instance of dominant bit following a stream of less than 11 |
Kojto | 90:cb3d968589d8 | 1550 | * consecutive recessive bits, the internal counter resets itself to zero without affecting |
Kojto | 90:cb3d968589d8 | 1551 | * the TXERRCNT value. If during system start-up, only one node is operating, |
Kojto | 90:cb3d968589d8 | 1552 | * then its TXERRCNT increases in each message it is trying to transmit, as a |
Kojto | 90:cb3d968589d8 | 1553 | * result of acknowledge errors (indicated by the ACKERR bit in the Error and Status |
Kojto | 90:cb3d968589d8 | 1554 | * Register). After the transition to 'Error Passive' state, the TXERRCNT does not |
Kojto | 90:cb3d968589d8 | 1555 | * increment anymore by acknowledge errors. Therefore the device never goes to |
Kojto | 90:cb3d968589d8 | 1556 | * the 'Bus Off' state. If the RXERRCNT increases to a value greater than 127, it |
Kojto | 90:cb3d968589d8 | 1557 | * is not incremented further, even if more errors are detected while being a |
Kojto | 90:cb3d968589d8 | 1558 | * receiver. At the next successful message reception, the counter is set to a value |
Kojto | 90:cb3d968589d8 | 1559 | * between 119 and 127 to resume to 'Error Active' state. |

Kojto | 90:cb3d968589d8 | 2171 | * are also used to represent FIFO interrupts when the Rx FIFO is enabled. When the |
Kojto | 90:cb3d968589d8 | 2172 | * bit MCR[RFEN] is set, the function of the 8 least significant interrupt flags |
Kojto | 90:cb3d968589d8 | 2173 | * BUF[7:0]I changes: BUF7I, BUF6I and BUF5I indicate operating conditions of |

Kojto | 90:cb3d968589d8 | 2536 | * |
Kojto | 90:cb3d968589d8 | 2537 | * This 5-bit field indicates how many CAN bits the Tx arbitration process start |
Kojto | 90:cb3d968589d8 | 2538 | * point can be delayed from the first bit of CRC field on CAN bus. This field |
Kojto | 90:cb3d968589d8 | 2539 | * can be written only in Freeze mode because it is blocked by hardware in other |
Kojto | 90:cb3d968589d8 | 2540 | * modes. This field is useful to optimize the transmit performance based on |
Kojto | 90:cb3d968589d8 | 2541 | * factors such as: peripheral/serial clock ratio, CAN bit timing and number of MBs. |
Kojto | 90:cb3d968589d8 | 2542 | * The duration of an arbitration process, in terms of CAN bits, is directly |
Kojto | 90:cb3d968589d8 | 2543 | * proportional to the number of available MBs and CAN baud rate and inversely |
Kojto | 90:cb3d968589d8 | 2544 | * proportional to the peripheral clock frequency. The optimal arbitration timing is |
Kojto | 90:cb3d968589d8 | 2545 | * that in which the last MB is scanned right before the first bit of the |
Kojto | 90:cb3d968589d8 | 2546 | * Intermission field of a CAN frame. Therefore, if there are few MBs and the system/serial |
Kojto | 90:cb3d968589d8 | 2547 | * clock ratio is high and the CAN baud rate is low then the arbitration can be |
Kojto | 90:cb3d968589d8 | 2548 | * delayed and vice-versa. If TASD is 0 then the arbitration start is not |
Kojto | 90:cb3d968589d8 | 2549 | * delayed, thus the CPU has less time to configure a Tx MB for the next arbitration, |
Kojto | 90:cb3d968589d8 | 2550 | * but more time is reserved for arbitration. On the other hand, if TASD is 24 then |
Kojto | 90:cb3d968589d8 | 2551 | * the CPU can configure a Tx MB later and less time is reserved for |
Kojto | 90:cb3d968589d8 | 2552 | * arbitration. If too little time is reserved for arbitration the FlexCAN may be not able |
Kojto | 90:cb3d968589d8 | 2553 | * to find winner MBs in time to compete with other nodes for the CAN bus. If the |
Kojto | 90:cb3d968589d8 | 2554 | * arbitration ends too much time before the first bit of Intermission field then |
Kojto | 90:cb3d968589d8 | 2555 | * there is a chance that the CPU reconfigures some Tx MBs and the winner MB is |
Kojto | 90:cb3d968589d8 | 2556 | * not the best to be transmitted. The optimal configuration for TASD can be |
Kojto | 90:cb3d968589d8 | 2557 | * calculated as: TASD = 25 - {f CANCLK * [MAXMB + 3 - (RFEN * 8) - (RFEN * RFFN * |

Kojto | 90:cb3d968589d8 | 2559 | * CANCLK is the Protocol Engine (PE) Clock (see section "Protocol Timing"), in |

Kojto | 90:cb3d968589d8 | 2585 | * This 4-bit field defines the number of Rx FIFO filters, as shown in the |
Kojto | 90:cb3d968589d8 | 2586 | * following table. The maximum selectable number of filters is determined by the MCU. |
Kojto | 90:cb3d968589d8 | 2587 | * This field can only be written in Freeze mode as it is blocked by hardware in |
Kojto | 90:cb3d968589d8 | 2588 | * other modes. This field must not be programmed with values that make the |
Kojto | 90:cb3d968589d8 | 2589 | * number of Message Buffers occupied by Rx FIFO and ID Filter exceed the number of |
Kojto | 90:cb3d968589d8 | 2590 | * Mailboxes present, defined by MCR[MAXMB]. Each group of eight filters occupies |
Kojto | 90:cb3d968589d8 | 2591 | * a memory space equivalent to two Message Buffers which means that the more |
Kojto | 90:cb3d968589d8 | 2592 | * filters are implemented the less Mailboxes will be available. Considering that |
Kojto | 90:cb3d968589d8 | 2593 | * the Rx FIFO occupies the memory space originally reserved for MB0-5, RFFN should |
Kojto | 90:cb3d968589d8 | 2594 | * be programmed with a value correponding to a number of filters not greater |
Kojto | 90:cb3d968589d8 | 2595 | * than the number of available memory words which can be calculated as follows: |
Kojto | 90:cb3d968589d8 | 2596 | * (SETUP_MB - 6) * 4 where SETUP_MB is the least between NUMBER_OF_MB and MAXMB. |
Kojto | 90:cb3d968589d8 | 2597 | * The number of remaining Mailboxes available will be: (SETUP_MB - 8) - (RFFN * |
Kojto | 90:cb3d968589d8 | 2598 | * 2) If the Number of Rx FIFO Filters programmed through RFFN exceeds the |
