Pin Function
The pin function is switched as shown below according to the combination of the OEn bit in
PWOERA of PWM, the P1nDDR bit, and operating mode.
The pin function is switched as shown below according to the combination of the OE1 bit in
PWOERA of PWM, the OEB bit in DACR of PWMX, the P11DDR bit, and operating mode.
The pin function is switched as shown below according to the combination of the OE0 bit in
PWOERA of PWM, the OEA bit in DACR of PWMX, the P10DDR bit, and operating mode.
