P45DDR
Pin Function
Note: * When bits CCLR1 and CCLR0 in TCR1 of TMR_1 are set to 1, this pin is used as the
OS3 to OS0
P44DDR
Pin Function
P43DDR
Pin Function
Note: * When the external clock is selected by bits CKS2 to CKS0 in TCR1 of TMR_1, this pin is
ICE
P42DDR
Pin Function
Note: * SDA1 is an NMOS-only output, and has direct bus drive capability.
P45/TMRI1
The pin function is switched as shown below according to the status of the P45DDR bit.
P44/TMO1
The pin function is switched as shown below according to the combination of the OS3 to OS0
bits in TCSR of TMR_1 and the P44DDR bit.
P43/TMCI1
The pin function is switched as shown below according to the status of the P43DDR bit.
P42/TMRI0/SDA1
The pin function is switched as shown below according to the combination of the ICE bit in
ICCR of IIC_1 and the P42DDR bit.
TMRI1 input pin.
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.
