garfieldsg 0:662207e34fba 966 *
garfieldsg 0:662207e34fba 967 * I2C data transactions are performed at the Sample Rate, as defined in
garfieldsg 0:662207e34fba 968 * Register 25. The user is responsible for ensuring that I2C data transactions
garfieldsg 0:662207e34fba 969 * to and from each enabled Slave can be completed within a single period of the
garfieldsg 0:662207e34fba 970 * Sample Rate.
garfieldsg 0:662207e34fba 971 *
garfieldsg 0:662207e34fba 972 * The I2C slave access rate can be reduced relative to the Sample Rate. This
garfieldsg 0:662207e34fba 973 * reduced access rate is determined by I2C_MST_DLY (Register 52). Whether a
garfieldsg 0:662207e34fba 974 * slave's access rate is reduced relative to the Sample Rate is determined by
garfieldsg 0:662207e34fba 975 * I2C_MST_DELAY_CTRL (Register 103).
garfieldsg 0:662207e34fba 976 *
garfieldsg 0:662207e34fba 977 * The processing order for the slaves is fixed. The sequence followed for
garfieldsg 0:662207e34fba 978 * processing the slaves is Slave 0, Slave 1, Slave 2, Slave 3 and Slave 4. If a
garfieldsg 0:662207e34fba 979 * particular Slave is disabled it will be skipped.
garfieldsg 0:662207e34fba 980 *
garfieldsg 0:662207e34fba 981 * Each slave can either be accessed at the sample rate or at a reduced sample
garfieldsg 0:662207e34fba 982 * rate. In a case where some slaves are accessed at the Sample Rate and some
garfieldsg 0:662207e34fba 983 * slaves are accessed at the reduced rate, the sequence of accessing the slaves
garfieldsg 0:662207e34fba 984 * (Slave 0 to Slave 4) is still followed. However, the reduced rate slaves will
garfieldsg 0:662207e34fba 985 * be skipped if their access rate dictates that they should not be accessed
garfieldsg 0:662207e34fba 986 * during that particular cycle. For further information regarding the reduced

garfieldsg 0:662207e34fba 2095 * and 3 on the auxiliary I2C interface. Data read by Slave 4 is stored in

garfieldsg 0:662207e34fba 2097 *
garfieldsg 0:662207e34fba 2098 * External sensor data is written to these registers at the Sample Rate as
garfieldsg 0:662207e34fba 2099 * defined in Register 25. This access rate can be reduced by using the Slave
garfieldsg 0:662207e34fba 2100 * Delay Enable registers (Register 103).
garfieldsg 0:662207e34fba 2101 *
garfieldsg 0:662207e34fba 2102 * External sensor data registers, along with the gyroscope measurement
garfieldsg 0:662207e34fba 2103 * registers, accelerometer measurement registers, and temperature measurement
garfieldsg 0:662207e34fba 2104 * registers, are composed of two sets of registers: an internal register set
garfieldsg 0:662207e34fba 2105 * and a user-facing read register set.
garfieldsg 0:662207e34fba 2106 *
garfieldsg 0:662207e34fba 2107 * The data within the external sensors' internal register set is always updated
garfieldsg 0:662207e34fba 2108 * at the Sample Rate (or the reduced access rate) whenever the serial interface
garfieldsg 0:662207e34fba 2109 * is idle. This guarantees that a burst read of sensor registers will read
garfieldsg 0:662207e34fba 2110 * measurements from the same sampling instant. Note that if burst reads are not
garfieldsg 0:662207e34fba 2111 * used, the user is responsible for ensuring a set of single byte reads
garfieldsg 0:662207e34fba 2112 * correspond to a single sampling instant by checking the Data Ready interrupt.
garfieldsg 0:662207e34fba 2113 *
garfieldsg 0:662207e34fba 2114 * Data is placed in these external sensor data registers according to
garfieldsg 0:662207e34fba 2115 * I2C_SLV0_CTRL, I2C_SLV1_CTRL, I2C_SLV2_CTRL, and I2C_SLV3_CTRL (Registers 39,
garfieldsg 0:662207e34fba 2116 * 42, 45, and 48). When more than zero bytes are read (I2C_SLVx_LEN > 0) from
garfieldsg 0:662207e34fba 2117 * an enabled slave (I2C_SLVx_EN = 1), the slave is read at the Sample Rate (as
garfieldsg 0:662207e34fba 2118 * defined in Register 25) or delayed rate (if specified in Register 52 and
garfieldsg 0:662207e34fba 2119 * 103). During each Sample cycle, slave reads are performed in order of Slave
garfieldsg 0:662207e34fba 2120 * number. If all slaves are enabled with more than zero bytes to be read, the
garfieldsg 0:662207e34fba 2121 * order will be Slave 0, followed by Slave 1, Slave 2, and Slave 3.
garfieldsg 0:662207e34fba 2122 *
garfieldsg 0:662207e34fba 2123 * Each enabled slave will have EXT_SENS_DATA registers associated with it by
garfieldsg 0:662207e34fba 2124 * number of bytes read (I2C_SLVx_LEN) in order of slave number, starting from
garfieldsg 0:662207e34fba 2125 * EXT_SENS_DATA_00. Note that this means enabling or disabling a slave may
garfieldsg 0:662207e34fba 2126 * change the higher numbered slaves' associated registers. Furthermore, if
garfieldsg 0:662207e34fba 2127 * fewer total bytes are being read from the external sensors as a result of
garfieldsg 0:662207e34fba 2128 * such a change, then the data remaining in the registers which no longer have
garfieldsg 0:662207e34fba 2129 * an associated slave device (i.e. high numbered registers) will remain in
garfieldsg 0:662207e34fba 2130 * these previously allocated registers unless reset.
garfieldsg 0:662207e34fba 2131 *
garfieldsg 0:662207e34fba 2132 * If the sum of the read lengths of all SLVx transactions exceed the number of
garfieldsg 0:662207e34fba 2133 * available EXT_SENS_DATA registers, the excess bytes will be dropped. There
garfieldsg 0:662207e34fba 2134 * are 24 EXT_SENS_DATA registers and hence the total read lengths between all
garfieldsg 0:662207e34fba 2135 * the slaves cannot be greater than 24 or some bytes will be lost.
garfieldsg 0:662207e34fba 2136 *
garfieldsg 0:662207e34fba 2137 * Note: Slave 4's behavior is distinct from that of Slaves 0-3. For further
garfieldsg 0:662207e34fba 2138 * information regarding the characteristics of Slave 4, please refer to
garfieldsg 0:662207e34fba 2139 * Registers 49 to 53.
garfieldsg 0:662207e34fba 2140 *
garfieldsg 0:662207e34fba 2141 * EXAMPLE:
garfieldsg 0:662207e34fba 2142 * Suppose that Slave 0 is enabled with 4 bytes to be read (I2C_SLV0_EN = 1 and
garfieldsg 0:662207e34fba 2143 * I2C_SLV0_LEN = 4) while Slave 1 is enabled with 2 bytes to be read so that
garfieldsg 0:662207e34fba 2144 * I2C_SLV1_EN = 1 and I2C_SLV1_LEN = 2. In such a situation, EXT_SENS_DATA _00
garfieldsg 0:662207e34fba 2145 * through _03 will be associated with Slave 0, while EXT_SENS_DATA _04 and 05
garfieldsg 0:662207e34fba 2146 * will be associated with Slave 1. If Slave 2 is enabled as well, registers
garfieldsg 0:662207e34fba 2147 * starting from EXT_SENS_DATA_06 will be allocated to Slave 2.
garfieldsg 0:662207e34fba 2148 *
garfieldsg 0:662207e34fba 2149 * If Slave 2 is disabled while Slave 3 is enabled in this same situation, then
garfieldsg 0:662207e34fba 2150 * registers starting from EXT_SENS_DATA_06 will be allocated to Slave 3
garfieldsg 0:662207e34fba 2151 * instead.
garfieldsg 0:662207e34fba 2152 *
garfieldsg 0:662207e34fba 2153 * REGISTER ALLOCATION FOR DYNAMIC DISABLE VS. NORMAL DISABLE:
garfieldsg 0:662207e34fba 2154 * If a slave is disabled at any time, the space initially allocated to the
garfieldsg 0:662207e34fba 2155 * slave in the EXT_SENS_DATA register, will remain associated with that slave.
garfieldsg 0:662207e34fba 2156 * This is to avoid dynamic adjustment of the register allocation.
garfieldsg 0:662207e34fba 2157 *
garfieldsg 0:662207e34fba 2158 * The allocation of the EXT_SENS_DATA registers is recomputed only when (1) all
garfieldsg 0:662207e34fba 2159 * slaves are disabled, or (2) the I2C_MST_RST bit is set (Register 106).
garfieldsg 0:662207e34fba 2160 *
garfieldsg 0:662207e34fba 2161 * This above is also true if one of the slaves gets NACKed and stops
garfieldsg 0:662207e34fba 2162 * functioning.
