Pin Function
The pin function is switched as shown below according to the state of the P43DDR bit.
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_1, the IIC1AS and the IIC1BS bits in PGCTL*
P42ICE = ICE
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of TMR_0 and the P41DDR bit.
The pin function is switched as shown below according to the state of the P40DDR bit.
*
1. SDA1 is an NMOS-only output, and has direct bus drive capability.
2. The program development tool (emulator) does not support the function of PGCTL.

When the external clock is selected by the bits CKS2 to CKS0 in TCR1 of TMR_1, this
pin is used as the TMCI1 input pin.
When bits CCLR1 and CCLR0 in TCR0 of TMR_0 are set to 1, this pin is used as the
TMRI0 input pin. When the P42 output pin is set, the output type is NMOS push-pull
output.
Thus P42ICE is treated as ICE.
When an external clock is selected with bits CKS2 to CKS0 in TCR0 of TMR_0, this pin
is used as the TMCI0 input pin.
