Port A has built-in programmable input pull-up transistors that are available in all modes.
An input pull-up transistor is turned on if 1 is written in the corresponding PAODR bit while the
corresponding PADDR bit is cleared to 0. The input pull-ups are turned off by a reset and in
hardware standby mode.
Table 7.22 indicates the states of the input pull-up transistors in each operating mode.
