• PA3/A19, PA2/A18, PA1/A17, PA20/A16
xx = 19 to 16, n = 3 to 0
10.9.8
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, 2, 5, and 6, and by all pins in
modes 4, and 7. input pull-up MOS can be specified as on or off on a bit-by-bit basis.
Table 10.2 summarizes the Input Pull-Up MOS states.
