Note: * A high-level signal is output when the MOS pull-up is in the on state.
8.5.5 MOS Input Pull-Up
Port 6 has a built-in MOS pull-up function that can be controlled by software. When a PCR6 bit is
cleared to 0, setting the corresponding PUCR6 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.
