(5) IIC function expansion register 0 (IICX0)
(6) I
This register sets the function expansion of I
IICX0 is 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 selection register 0 (IICCL0) (see 18.3 (6) I
method).
Set IICX0 while bit 7 (IICE0) of IIC control register 0 (IICC0) is 0.
Reset signal generation clears IICX0 to 00H.
The I
For example, the I
