data, and the slave device returns an acknowlede signal.
The transmission procedure and operations by which data is sequentially transmitted in
synchronization with ICDR write operations, are described below.
[1] Set the ICE bit in ICCR to l. Set bits MLS, WAIT, and CKS2 to CKS0 in ICMR, and bit IICX
[2] Read the BBSY flag to confirm that the bus is free.
[3] Set the MST and TRS bits to 1 in ICCR to select master transmit mode.
[4] Write 1 to BBSY and 0 to SCP. This switches SDA from high to low when SCL is high, and
[5] When the start condition is generated, the IRIC and IRTR flags are set to 1. If the IEIC bit in

Then clear the IRIC flag to indicate the end of transfer.
Master Transmit Operation
