Description added
… Eight serial clock pulses are output in the transfer of one
character, and when no transfer is performed, the clock is fixed
high. However, during receive-only operation the
synchronization clock is output until an overrun error occurs or
the RE bit is cleared to 0. When receive operation in single-
character units is desired, select an external clock as the clock
source.

Due to factors such as load conditions, it may not be
possible to obtain the designated transfer rate when
the value of IICX is 0 and the peripheral clock φ
frequency exceeds 16 MHz. Set IICX to 1 when Pφ is
greater than 16 MHz.
