(7) IIC division clock select registers 0, 1 (OCKS0, OCKS1)
(8) IIC shift registers 0 to 2 (IIC0 to IIC2)
The OCKSm register controls the I
These registers control the I
via the OCKS1 register.
These registers can be read or written in 8-bit units.
Reset sets these registers to 00H.
The IICn register is used for serial transmission/reception (shift operations) synchronized with the serial clock.
These registers can be read or written in 8-bit units, but data should not be written to the IICn register during a
data transfer.
Access (read/write) the IICn register only during the wait period. Accessing this register in communication
states other than the wait period is prohibited. However, for the master device, the IICn register can be written
once only after the transmission trigger bit (IICCn.STTn bit) has been set to 1.
A wait state is released by writing the IICn register during the wait period, and data transfer is started (n = 0 to 2).
Reset sets these registers to 00H.
