8.2.4 Pin Functions
• P17/A7/PW7 to P10/A0/PW0
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.

8.2.5 Port 1 Input Pull-Up MOS
Port 1 has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
Table 8.2 summarizes the input pull-up MOS states.
