Each pin of port D has an independent 1-bit wide output function. The output
structure is P-channel open-drain.
1-bit I/O port. For input use, set the latch of the specified bit to “0.” When the built-
in pull-down transistor is turned on, the key-on wakeup function using “H” level
sense and the pull-down transistor become valid. The output structure is P-channel
open-drain.
