Input
Low-threshold input-only port.
Can be used for functions such as key data acquisition.
Pull-down resistors can be specified as an option. This
option is specified in a 4-pin unit, and cannot be
specified in single pin units.
Input is disabled in backup mode.
Output
Output-only ports.
Since the output transistor circuits are unbalanced
CMOS outputs, these outputs can be effectively used for
functions such as key scan timing.
These ports go to the high-impedance state in backup
mode.
These ports output a low level after a reset
(when RES is set low).
Output-only port.
These are normal CMOS outputs.
This port goes to the high-impedance state in backup
mode.
This port outputs a low level after a reset
(when RES is set low).
I/O
I/O port.
The input/output state is selected as follows: Once an
input instruction (IN, TPT, or TPF) is executed, the port
switches to the input state and remains in that state.
Once an output instruction (OUT, SPB, RPB) is executed,
the port switches to the output state and remains in that
state. Note that PE1, PE2, and PE3 are also used as the
serial I/O port. These pins go to the input state after a
reset.
This port goes to the input state with input disabled in
backup mode.
I/O port.
The FPC instruction is used for switching the port
function between input and output. Input or output can
be specified in single pin units.
This port is set to its input function after a reset.
This port goes to the input state with input disabled in
backup mode.
