Control in I
(1) Acknowledge mode specification
(2) Select number of transfer bits
(3) Serial clock
TMP92CM22 generates an additional clock pulse for an acknowledge signal when
operating in master mode. In the transmitter mode during the clock pulse cycle, the
SDA pin is released in order to receive the acknowledge signal from the receiver. In the
receiver mode during the clock pulse cycle, the SDA pin is set to the low in order to
generate the acknowledge signal.
