This register sets the function expansion of I
IICX0 can be set by a 1-bit or 8-bit memory manipulation instruction. The CLX0 bit is set in combination with
bits 3, 1, and 0 (SMC0, CL01, and CL00) of IIC clock select register 0 (IICCL0) (see 12.5.4 Transfer clock
setting method).
Set IICX0 while bit 7 (IICE0) of IIC control register 0 (IICC0) is 0.
Reset signal generation clears this register to 00H.
