Pin Functions
The relationship between register setting values and pin functions are as follows in each operating
mode. In the tables, the symbol “—” stands for Don't care.
Extended Mode:
The function of port 1 pins is switched as shown below according to the P1nDDR bit.

Single-Chip Mode:
The function of port 1 pins is switched as shown below according to the combination of the OEn
bit in PWOERA of PWM and the P1nDDR bit.
