8.11.4
Port A has a built-in MOS input pull-up function that can be controlled by software. This MOS
input pull-up function can be used in any operating mode, and can be specified as on or off on a
bit-by-bit basis.
When a PADDR bit is cleared to 0, setting the corresponding PAODR bit to 1 turns on the MOS
input pull-up for that pin. The MOS input pull-up for pins PA7 to PA4 is always off when IICS is
set to 1. When the keyboard buffer control pin function is selected for pins PA7 to PA2, the MOS
input pull-up is always off.
The MOS input pull-up function is in the off state after a reset and in hardware standby mode. The
prior state is retained in software standby mode.
Table 8.24 summarizes the MOS input pull-up states.
