Note: * A high-level signal is output when the MOS pull-up is in the on state.
8.2.5
Port 1 has a built-in MOS input pull-up function that can be controlled by software. When a
PCR1 bit is cleared to 0, setting the corresponding PUCR1 bit to 1 turns on the MOS input pull-up
for that pin. The MOS input pull-up function is in the off state after a reset.
