(3) IIC flag register 0 (IICF0)
IICF0 is a register that sets the operation mode of I
2
C0 and indicates the status of the I
2
C bus.
This register can be read or written in 8-bit or 1-bit units. However, the STCF0 and IICBSY0 bits are read-only.
The IICRSV0 bit can be used to enable/disable the communication reservation function (refer to
16.13
Communication Reservation
).
The STCEN0 bit can be used to set the initial value of the IICBSY0 bit (refer to
16.14 Cautions
).
The IICRSV0 and STCEN0 bits can be written only when the operation of I
2
C0 is disabled (IICC0.IICE0 bit = 0).
When operation is enabled, the IICF0 register can be read.
Reset sets this register to 00H.
