frame data following the start condition indicates the 7-bit slave address and transmit/receive
direction (R/W).
To determine the end of the transfer, the IRIC flag is cleared to 0. After writing to ICDR,
clear IRIC continuously so no other interrupt handling routine is executed. If the time for
transmission of one frame of data has passed before the IRIC clearing, the end of
transmission cannot be determined. The master device sequentially sends the transmission
clock and the data written to ICDR. The selected slave device (i.e. the slave device with the
matching slave address) drives SDA low at the 9th transmit clock pulse and returns an
acknowledge signal.

As indicating the end of the transfer, the IRIC flag is cleared to 0. Perform the ICDR write

synchronization with the internal clock until the next transmit data is written.
Confirm that the slave device has been acknowledged (ACKB bit is 0). When there is still
data to be transmitted, go to step [9] to continue the next transmission operation. When the
slave device has not acknowledged (ACKB bit is set to 1), operate step [12] to end
transmission.
Write 0 to ACKE in ICCR, to clear received ACKB contents to 0. Write 0 to BBSY and SCP
in ICCR. This changes SDA from low to high when SCL is high, and generates the stop
condition.
