CHAPTER 19 I
C BUS
(3) IIC flag registers 0 to 2 (IICF0 to IICF2)
2
2
The IICFn register sets the I
C0n operation mode and indicates the I
C bus status.
These registers can be read or written in 8-bit or 1-bit units. However, the STCFn and IICBSYn bits are read-
only.
IICRSVn enables/disables the communication reservation function (see 19.14 Communication Reservation).
The initial value of the IICBSYn bit is set by using the STCENn bit (see 19.15 Cautions).
2
The IICRSVn and STCENn bits can be written only when operation of I
C0n is disabled (IICCn.IICEn bit = 0).
After operation is enabled, IICFn can be read (n = 0 to 2).
Reset sets these registers to 00H.
