communication) is necessary.

performed during the main processing.

interrupts, conditions are confirmed by flags).

The following shows the processing procedure of the slave operation.
Basically, the operation of the slave device is event-driven.
The following description assumes that data communication does not support extension codes. Also, it is assumed
Therefore, the following three flags are prepared so that the data transfer processing can be performed by
The following shows the operation of the main processing block during slave operation.
Start I
For transmission, repeat the transmission operation until the master device stops returning ACK. When the master

This flag indicates the following communication statuses.
Clear mode:
Communication mode: Data communication in progress (valid address detection stop condition detection,
This flag indicates that data communication is enabled. This is the same status as an INTIIC interrupt during
normal data transfer. This flag is set in the interrupt processing block and cleared in the main processing
block. The ready flag for the first data for transmission is not set in the interrupt processing block, so the first
data is transmitted without clearance processing (the address match is regarded as a request for the next
data).
This flag indicates the direction of communication and is the same as the value of the IICS0.TRC0 bit.
