(5) IIC function expansion registers n (IICXn)
(6) I
The IICXn registers set I
These registers can be read or written in 8-bit or 1-bit units.
Setting of the CLXn bit is performed in combination with the SMCn, CLn1, and CLn0 bits of the IICCLn register
and the OCKSTHm, OCKSm1, and OCKSm0 bits of the OCKSm register (see 20.4 (6) I
setting method) (m = 0 to 2).
Set the IICXn registers when the IICCn.IICEn bit = 0.
Reset sets these registers to 00H.
The I
For example, the I
is calculated using following expression.
The clock to be selected can be set by combining of the SMCn, CLn1, and CLn0 bits of the IICCLn register, the
CLXn bit of the IICXn register, and the OCKSTHm, OCKSm1, and OCKSm0 bits of the OCKSm register (m = 0
to 2).
