Slave Receive Operation
2
In I
C bus format slave receive mode, the master device outputs the transmit clock and transmit
data, and the slave device returns an acknowledge signal.
The slave device operates as the device specified by the master device when the slave address in
the first frame following the start condition that is issued by the master device matches its own
address.
Receive Operation Using the HNDS Function (HNDS = 1):
Figure 16.18 shows the sample flowchart for the operations in slave receive mode (HNDS = 1).
