3.5.2 Port 1 (P10 ~ P17)
Port 1 is the 8-bit general-purpose I/O port P1, each bit of
which can be set to input or output. The port 1 control register
P1CR is used to set input or output. Reset operations clear all
output latch and the control register bits to “0” and sets all port
1 bits to the input mode.
In addition to the general-purpose I/O port function, port 1
also functions as an address bus (A8 ~ A15). This is specified
by setting the external extended specification register
IRFL<EXT> to “1” and setting P1CR to the output mode.
When the P1CR cleared to “0”, port 1 is set to the input mode,
regardless of the external extended specification register
value. IRF2 <EXT> also controls P30 (RD) and P31 (WR), P80
(ALE).
