Port 0 (P07–P00)
Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are
configured under software control as a nibble I/O port. The output drivers are push-pull or
open-drain controlled by bit D2 in the PCON register.
If one or both nibbles are needed for I/O operation, they must be configured by writing to
the Port 0 mode register. After a hardware reset, Port 0 is configured as an input port.
An optional pull-up transistor is available as a mask option on all Port 0 bits with nibble
select.

Internal pull-ups are disabled on any given pin or group of port pins
when programmed into output mode.
The Port 0 direction is reset to be input following an SMR.
