3.5.2 Port 1 (P10 ~ P17)
Port 1 is an 8-bit general-purpose I/O port P1 whose I/O function
is specified by the control register P1CR in bit. All bits of the
output latch and the control register are initialized to “0” by
resetting, whereby Port 1 is put in the input mode.
In addition to the general-purpose I/O port function, it
functions as a data bus (A8 ~ A15). The address bus fucntion
can be specified by setting the external externsion control regis-
ter P2FR <EXT> to “1”, and also setting the Port 1 control regis-
ter P1CR to the output mode. When the value of the Port 1
control is set to “0”, Port 1 turns to the input mode regardless of
the value of the exernal extension control register. The <EXT>
register is reset to “0” whereby Port 1 turns to the general-pur-
pose I/O mode.
