12.5.6 Wait

The wait is used to notify the communication partner that a device (master or slave) is preparing to transmit or receive

data (i.e., is in a wait state).

Setting the SCLAn pin to low level notifies the communication partner of the wait state. When wait state has been

canceled for both the master and slave devices, the next data transfer can begin.

Figure 12-20. Wait (1/2)

(1) When master device has a nine-clock wait and slave device has an eight-clock wait

(master transmits, slave receives, and ACKEn = 1)
