NAME
FUNCTION
Port 1 (I/O). Port 1 functions as both an 8-bit bidirectional I/O port
and an alternate functional interface for Timer 2 I/O and new
external interrupts. The reset condition of Port 1 is with all bits at
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 overcomes the weak pullup. When software
writes a 0 to any port pin, the DS80C310 activates 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 causes 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 the output high
(and input) state. The alternate modes of Port 1 are outlined as
follows:

RST
Reset (Input). The RST input pin contains a Schmitt voltage input to
recognize external active-high reset inputs. The pin also employs an
internal pulldown resistor to allow for a combination of wired-OR
external reset sources.
