In I
and returns an acknowledge signal. The slave device transmits data.
The master device transmits data containing the slave address and R/W (1: read) in the first frame
following the start condition issuance in master transmit mode, selects the slave device, and then
switches the mode for receive operation.
Receive Operation Using the HNDS Function (HNDS = 1):
Figure 15.10 shows the sample flowchart for the operations in master receive mode (HNDS = 1).

[1] Select receive mode.
[2] Start receiving. The first read is a dummy read.
[5] Read the receive data (for the second and subsequent read)
[3] Wait for 1 byte to be received.
[4] Clear IRIC.
[6] Set acknowledge data for the last reception.
[7] Read the receive data.
[8] Wait for 1 byte to be received.
[9] Clear IRIC.
[10] Read the receive data.
[11] Set stop condition issuance.
(Set IRIC at the rise of the 9th clock for the receive frame)
Dummy read to start receiving if the first frame is
the last receive data.
Generate stop condition.
