Table 8.10 Port 4 Pin Functions
Pin Selection Method and Pin Functions
P47/PWX1 The pin function is switched as shown below according to the combination of
bit OEB in DACR of 14-bit PWM, and bit P47DDR.
OEB 0 1
P47DDR 0 1
Pin function P47 input pin P47 output pin PWX1 output pin
P46/PWX0 The pin function is switched as shown below according to the combination of
bit OEA in DACR of 14-bit PWM, and bit P46DDR.
OEA 0 1
P46DDR 0 1
Pin function P46 input pin P46 output pin PWX0 output pin
P45/TMRI1/
HIRQ12/CSYNCI
The pin function is switched as shown below according to the combination of
the operating mode and bit P45DDR.

Pin function P45 input pin P45 output pin HIRQ12 output pin
TMRI1 input pin, CSYNCI input pin
When bits CCLR1 and CCLR0 in TCR1 of TMR1 are set to 1, this pin is used
as the TMRI1 input pin. It can also be used as the CSYNCI input pin.
P44/TMO1/
HIRQ1/HSYNCO
The pin function is switched as shown below according to the combination of
the operating mode, bits OS3 to OS0 in TCSR of TMR1, bit HOE in TCONRO
of the timer connection function, and bit P44DDR.
HOE 0 1
