Low threshold type dedicated input port
These pins can be used, for example, for key data acquisition.
Built-in pull-down resistors can be specified as an option. This
option is in 4-pin units, and cannot be specified for individual
pins.
Input through these pins is disabled in BACKUP mode.
Dedicated output ports
Since the output transistor impedances are unbalanced
CMOS, these pins can be effectively used for functions such
as key scan timing. These pins go to the output high
impedance state in BACKUP mode.
These pins go to the low level during a reset, i.e., when the
RES pin is low.
Dedicated output ports
These are normal CMOS outputs. These pins go to the output
high impedance state in BACKUP mode.
These pins go to the low level during a reset, i.e., when the
RES pin is low.
I/O port
These pins are switched between input and output as follows.
Once an input instruction (IN, TPT, or TPF) is executed, these
pins latch in the input mode. Once an output instruction (OUT,
SPB, or RPB) is executed, they latch in the output mode.
Note that PE1, PE2 and PE3 are also used as the serial I/O
port. These pins go to the input mode during a reset, i.e.,
when the RES pin is low.
In BACKUP mode these pins go to the input mode with input
disabled.
I/O port
These pins are switched between input and output by the
FPC instruction.
The I/O states of this port can be specified for individual pins.
These pins go to the input mode during a reset, i.e., when the
RES pin is low.
In BACKUP mode these pins go to the input mode with input
disabled.
Dedicated input port
Input through these pins is disabled in BACKUP mode.
