+// EXT_SENS_DATA_* registers

+/** Read single byte from external sensor data register.
+ * These registers store data read from external sensors by the Slave 0, 1, 2,
+ * and 3 on the auxiliary I2C interface. Data read by Slave 4 is stored in
+ * I2C_SLV4_DI (Register 53).
+ *
+ * External sensor data is written to these registers at the Sample Rate as
+ * defined in Register 25. This access rate can be reduced by using the Slave
+ * Delay Enable registers (Register 103).
+ *
+ * External sensor data registers, along with the gyroscope measurement
+ * registers, accelerometer measurement registers, and temperature measurement
+ * registers, are composed of two sets of registers: an internal register set
+ * and a user-facing read register set.
+ *
+ * The data within the external sensors' internal register set is always updated
+ * at the Sample Rate (or the reduced access rate) whenever the serial interface
+ * is idle. This guarantees that a burst read of sensor registers will read
+ * measurements from the same sampling instant. Note that if burst reads are not
+ * used, the user is responsible for ensuring a set of single byte reads
+ * correspond to a single sampling instant by checking the Data Ready interrupt.
+ *
+ * Data is placed in these external sensor data registers according to
+ * I2C_SLV0_CTRL, I2C_SLV1_CTRL, I2C_SLV2_CTRL, and I2C_SLV3_CTRL (Registers 39,
+ * 42, 45, and 48). When more than zero bytes are read (I2C_SLVx_LEN > 0) from
+ * an enabled slave (I2C_SLVx_EN = 1), the slave is read at the Sample Rate (as
+ * defined in Register 25) or delayed rate (if specified in Register 52 and
+ * 103). During each Sample cycle, slave reads are performed in order of Slave
+ * number. If all slaves are enabled with more than zero bytes to be read, the
+ * order will be Slave 0, followed by Slave 1, Slave 2, and Slave 3.
+ *
+ * Each enabled slave will have EXT_SENS_DATA registers associated with it by
+ * number of bytes read (I2C_SLVx_LEN) in order of slave number, starting from
+ * EXT_SENS_DATA_00. Note that this means enabling or disabling a slave may
+ * change the higher numbered slaves' associated registers. Furthermore, if
+ * fewer total bytes are being read from the external sensors as a result of
+ * such a change, then the data remaining in the registers which no longer have
+ * an associated slave device (i.e. high numbered registers) will remain in
+ * these previously allocated registers unless reset.
+ *
+ * If the sum of the read lengths of all SLVx transactions exceed the number of
+ * available EXT_SENS_DATA registers, the excess bytes will be dropped. There
+ * are 24 EXT_SENS_DATA registers and hence the total read lengths between all
+ * the slaves cannot be greater than 24 or some bytes will be lost.
+ *
+ * Note: Slave 4's behavior is distinct from that of Slaves 0-3. For further
+ * information regarding the characteristics of Slave 4, please refer to
+ * Registers 49 to 53.
+ *
+ * EXAMPLE:
+ * Suppose that Slave 0 is enabled with 4 bytes to be read (I2C_SLV0_EN = 1 and
+ * I2C_SLV0_LEN = 4) while Slave 1 is enabled with 2 bytes to be read so that
+ * I2C_SLV1_EN = 1 and I2C_SLV1_LEN = 2. In such a situation, EXT_SENS_DATA _00
+ * through _03 will be associated with Slave 0, while EXT_SENS_DATA _04 and 05
+ * will be associated with Slave 1. If Slave 2 is enabled as well, registers
+ * starting from EXT_SENS_DATA_06 will be allocated to Slave 2.
+ *
+ * If Slave 2 is disabled while Slave 3 is enabled in this same situation, then
+ * registers starting from EXT_SENS_DATA_06 will be allocated to Slave 3
+ * instead.
+ *
+ * REGISTER ALLOCATION FOR DYNAMIC DISABLE VS. NORMAL DISABLE:
+ * If a slave is disabled at any time, the space initially allocated to the
+ * slave in the EXT_SENS_DATA register, will remain associated with that slave.
+ * This is to avoid dynamic adjustment of the register allocation.
+ *
+ * The allocation of the EXT_SENS_DATA registers is recomputed only when (1) all
+ * slaves are disabled, or (2) the I2C_MST_RST bit is set (Register 106).
+ *
+ * This above is also true if one of the slaves gets NACKed and stops
+ * functioning.
