Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bit OEB in DACR of 14-bit PWM, and bit P47DDR.
The pin function is switched as shown below according to the combination of
bit OEA in DACR of 14-bit PWM, and bit P46DDR.
The pin function is switched as shown below according to the combination of
the operating mode and bit P45DDR.
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.
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.
