Note: * A high-level signal is output when the MOS pull-up is in the on state.
In the HD64F38024 the previous pin state is retained.
8.5.5 MOS Input Pull-Up
Port 5 has a built-in MOS input pull-up function that can be controlled by software. When a
PCR5 bit is cleared to 0, setting the corresponding PUCR5 bit to 1 turns on the MOS pull-up for
that pin. The MOS pull-up function is in the off state after a reset.
