Port 1, I/O.
Port 1 can function as an 8-bit bidirectional I/O port, the
nonmultiplexed A0–A7 signals (when the
MUX pin = 1), and as an
alternate interface for internal resources. Setting the SP1EC bit
relocates RXD1 and TXD1 to Port 5. The reset condition of Port 1 is
all bits at logic 1 through 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, a
strong pulldown is activated 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 activates 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.

A15–A8 (Port 2), Output.
Port 2 serves as the MSB for external
addressing. The port automatically asserts the address MSB during
external ROM and RAM access. Although the Port 2 SFR exists, the
SFR value never appears on the pins (due to memory access).
Therefore, accessing the Port 2 SFR is only useful for MOVX A, @Ri
or MOVX @Ri, A instructions, which use the Port 2 SFR as the
external address MSB.

P3.0–P3.7
Port 3, I/O.
Port 3 functions as an 8-bit bidirectional I/O port and as an
alternate interface for several resources found on the traditional 8051.
The reset condition of Port 1 is all bits at logic 1 through 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 activates 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.
