9.1.4
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.
Note: n = 7 to 0
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.
Note: n = 7 to 0
9.1.5
Port 1 has a built-in input pull-up MOS that can be controlled by software. This input pull-up
MOS can be used regardless of the operating mode. Table 9.2 summarizes the input pull-up MOS
states.
