Port 4, I/O.
Port 4 can function as an 8-bit, bidirectional I/O port, and
as the source for external address and chip enable signals for
program and data memory. Port pins are configured as I/O or
memory signals via the P4CNT register. The reset condition of Port 1
is all bits at logic 1 via a weak pullup. The logic 1 state also serves as
an input mode, since external circuits writing to the port can overdrive
the weak pullup. When software clears any port pin to 0, the device
activates a strong pulldown that remains on until either a 1 is written
to the port pin or a reset occurs. Writing a 1 after the port has been at
0 will activate a strong transition driver, followed by a weaker
sustaining pullup. Once the momentary strong driver turns off, the
port once again becomes the output (and input) high state.

Port 5, I/O.
Port 5 can function as an 8-bit, bidirectional I/O port, the
CAN interface, or as peripheral enable signals. Setting the SP1EC bit
will relocate the RXD1 and TXD1 functions to P5.3-P5.2 as described
in the High-Speed Microcontroller User’s Guide: DS80C390
Supplement
. The reset condition of Port 1 is all bits at logic 1 via a
weak pullup. The logic 1 state also serves as an input mode, since
external circuits writing to the port can overdrive the weak pullup.
When software clears any port pin to 0, the device activates a strong
pulldown that remains on until either a 1 is written to the port pin or a
reset occurs. Writing a 1 after the port has been at 0 will activate a
strong transition driver, followed by a weaker sustaining pullup. Once
the momentary strong driver turns off, the port once again becomes
the output (and input) high state.
