RESET
A high level on this pin for one machine cycle
while the oscillator is running resets the device.
An internal diffused resistor to

Port 3
is an 8-bit quasi-bidirectional port with internal
pull-up transistors. Port 3 pins that have “1”s
written to them are pulled high by the internal
pull-up transistors and in that state can be used
as inputs. As inputs, Port 3 pins being
externally pulled low will source current (
I
IL
, in
the DC characteristics) because of the internal
pullup transistors. The output latch
corresponding secondary function must be
programmed to a one (1) for that function to
operate (except for TxD and WR).
The secondary functions are assigned to the
pins of Port 3 as follows:
