8.5.2.2 Transmit Mode

In slave transmit mode, the first byte transmitted by the master is the 7-bit slave address followed by the high R/W bit. This byte places the slave into transmit mode and indicates that the ADS101x are being read from. The next byte transmitted by the slave is the most significant byte of the register that is indicated by the register address pointer bits, P[1:0]. This byte is followed by an acknowledgment from the master. The remaining least significant byte is then sent by the slave and is followed by an acknowledgment from the master. The master may terminate transmission after any byte by not acknowledging or issuing a START or STOP condition.
