10.9.7 Port A Input Pull-Up MOS States
Port A has a built-in input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be used by pins PA7 to PA5 in modes 1 and 2, and by all pins in modes
3, 4, and 7. The input pull-up MOS can be specified as on or off on a bit-by-bit basis.
Table 10.3 summarizes the input pull-up MOS states. The input pull-up MOS should not be turned
on when the SCI is used.
