garfieldsg 0:662207e34fba 912 * (Slave 0 to Slave 4) is still followed. However, the reduced rate slaves will

garfieldsg 0:662207e34fba 1940 * an enabled slave (I2C_SLVx_EN = 1), the slave is read at the Sample Rate (as
garfieldsg 0:662207e34fba 1941 * defined in Register 25) or delayed rate (if specified in Register 52 and
garfieldsg 0:662207e34fba 1942 * 103). During each Sample cycle, slave reads are performed in order of Slave
garfieldsg 0:662207e34fba 1943 * number. If all slaves are enabled with more than zero bytes to be read, the
garfieldsg 0:662207e34fba 1944 * order will be Slave 0, followed by Slave 1, Slave 2, and Slave 3.
garfieldsg 0:662207e34fba 1945 *
garfieldsg 0:662207e34fba 1946 * Each enabled slave will have EXT_SENS_DATA registers associated with it by
garfieldsg 0:662207e34fba 1947 * number of bytes read (I2C_SLVx_LEN) in order of slave number, starting from
garfieldsg 0:662207e34fba 1948 * EXT_SENS_DATA_00. Note that this means enabling or disabling a slave may
garfieldsg 0:662207e34fba 1949 * change the higher numbered slaves' associated registers. Furthermore, if
garfieldsg 0:662207e34fba 1950 * fewer total bytes are being read from the external sensors as a result of
garfieldsg 0:662207e34fba 1951 * such a change, then the data remaining in the registers which no longer have
garfieldsg 0:662207e34fba 1952 * an associated slave device (i.e. high numbered registers) will remain in
garfieldsg 0:662207e34fba 1953 * these previously allocated registers unless reset.
garfieldsg 0:662207e34fba 1954 *
garfieldsg 0:662207e34fba 1955 * If the sum of the read lengths of all SLVx transactions exceed the number of
garfieldsg 0:662207e34fba 1956 * available EXT_SENS_DATA registers, the excess bytes will be dropped. There
garfieldsg 0:662207e34fba 1957 * are 24 EXT_SENS_DATA registers and hence the total read lengths between all
garfieldsg 0:662207e34fba 1958 * the slaves cannot be greater than 24 or some bytes will be lost.
garfieldsg 0:662207e34fba 1959 *
garfieldsg 0:662207e34fba 1960 * Note: Slave 4's behavior is distinct from that of Slaves 0-3. For further
garfieldsg 0:662207e34fba 1961 * information regarding the characteristics of Slave 4, please refer to
garfieldsg 0:662207e34fba 1962 * Registers 49 to 53.
garfieldsg 0:662207e34fba 1963 *
garfieldsg 0:662207e34fba 1964 * EXAMPLE:
garfieldsg 0:662207e34fba 1965 * Suppose that Slave 0 is enabled with 4 bytes to be read (I2C_SLV0_EN = 1 and
garfieldsg 0:662207e34fba 1966 * I2C_SLV0_LEN = 4) while Slave 1 is enabled with 2 bytes to be read so that
garfieldsg 0:662207e34fba 1967 * I2C_SLV1_EN = 1 and I2C_SLV1_LEN = 2. In such a situation, EXT_SENS_DATA _00
garfieldsg 0:662207e34fba 1968 * through _03 will be associated with Slave 0, while EXT_SENS_DATA _04 and 05
garfieldsg 0:662207e34fba 1969 * will be associated with Slave 1. If Slave 2 is enabled as well, registers
garfieldsg 0:662207e34fba 1970 * starting from EXT_SENS_DATA_06 will be allocated to Slave 2.
garfieldsg 0:662207e34fba 1971 *
garfieldsg 0:662207e34fba 1972 * If Slave 2 is disabled while Slave 3 is enabled in this same situation, then
garfieldsg 0:662207e34fba 1973 * registers starting from EXT_SENS_DATA_06 will be allocated to Slave 3
garfieldsg 0:662207e34fba 1974 * instead.
garfieldsg 0:662207e34fba 1975 *
garfieldsg 0:662207e34fba 1976 * REGISTER ALLOCATION FOR DYNAMIC DISABLE VS. NORMAL DISABLE:
garfieldsg 0:662207e34fba 1977 * If a slave is disabled at any time, the space initially allocated to the
garfieldsg 0:662207e34fba 1978 * slave in the EXT_SENS_DATA register, will remain associated with that slave.
garfieldsg 0:662207e34fba 1979 * This is to avoid dynamic adjustment of the register allocation.
garfieldsg 0:662207e34fba 1980 *
garfieldsg 0:662207e34fba 1981 * The allocation of the EXT_SENS_DATA registers is recomputed only when (1) all
garfieldsg 0:662207e34fba 1982 * slaves are disabled, or (2) the I2C_MST_RST bit is set (Register 106).
garfieldsg 0:662207e34fba 1983 *
garfieldsg 0:662207e34fba 1984 * This above is also true if one of the slaves gets NACKed and stops
garfieldsg 0:662207e34fba 1985 * functioning.
