Note: n = 7 to 0
8.2.5
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.

Pin Function
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.
Input pull-up MOS is always off.
