VMX51C900 EA pin is held at 0V during reset, or
when a MOVX instruction is executed.
The P0 register located at address 80h controls the
individual pin direction when configured as an I/O. The
P0 register is bit-addressable.

For each bit of the P0 register correspond
to an I/O line:
0: Output transistor pull the line to 0V
1: The output transistor is blocked so the
pull-up brings the I/O to 5V.
Port 2
Port P2 is very similar to Port1 and Port3, the
difference being that the alternate function of P2 is to
act as the upper address bus (A8-A15) when the EA
line of the VMX51C900 is held low at reset time or
when a MOVX instruction is executed.
Like the P1, P2 and P3 registers, the P2 register is bit-
addressable.

Port P0 and P2 as Address and Data Bus
The output stage may receive data from two sources:
The outputs of register P0 or the bus address
itself multiplexed with the data bus for P0
The outputs of the P2 register or the high byte
(A8 through A15) of the bus address for the P2
port

Address
When the ports are used as an address or data bus,
the special function registers P0 and P2 are
disconnected from the output stage, the 8 bits of the
P0 register are forced to 1 and the contents of the P2
register remains constant.
Port 1
The P1 register controls the direction of the Port 1 I/O
pins. Writing a 1 to the corresponding bit configures
the port as an output. This presents a logic 1 to the
corresponding I/O pin or allows the I/O pin to be used
as an input. Writing a 0 activates the output “pull-
down” transistor, which will force the corresponding I/O
line to a logic low.
