A8-15 (Port 2) -Output. Port 2 serves as the MSB for external
addressing. P2.7 is A15 and P2.0 is A8. The DS80C310 will
automatically place the MSB of an address on P2 for external
ROM and RAM access. Although Port 2 can be accessed like
an ordinary I/O port, the value stored on the Port 2 latch will
never be seen on the pins (due to memory access). Therefore
writing to Port 2 in software is only useful for the instructions
MOVX A, @ Ri or MOVX @ Ri, A. These instructions use the
Port 2 internal latch to supply the external address MSB; the
Port 2 latch value will be supplied as the address information.

P3.0-3.7
Port 3 - I/O. Port 3 functions as both an 8-bit bidirectional I/O
port and an alternate functional interface for external Interrupts,
Serial Port 0, Timer 0 and 1 Inputs, RD and WR strobes. The
reset condition of Port 3 is with all bits at a logic 1. In this
state, a weak pullup holds the port high. This condition also
serves as an input mode, since any external circuit that writes
to the port will overcome the weak pullup. When software
writes a 0 to any port pin, the DS80C310 will activate a strong
pulldown that remains on until either a 1 is written or a reset
occurs. Writing a 1 after the port has been at 0 will cause a
strong transition driver to turn on, followed by a weaker
sustaining pullup. Once the momentary strong driver turns off,
the port once again becomes both the output high and input
state. The alternate modes of Port 3 are outlined below.
