Port 1 is a 8-bit bidirectional
multifunction I/O port with
internal pull-up resistors.
Port 1 pins that have “1”
written to them are pulled
high by the internal pull-up
resistors and in that state
can be used as inputs.
----------
Port 1.7 has an alternated
function.
See Section on page 155.
Not connected.
Control output. Indicates a
write access to the internal
XRAM.
----------
It can be used as a write
strobe for writing data into
an external data RAM by a
MOVX instruction.
----------
This signal is also available
as P4.3
See Section on page 155.
