Input Port Options
The use of the low level hold transistor can be specified individually for each pin in the S1 to S4 and M1 to M4 ports.
1. The S port includes independent (in bit units) chattering exclusion circuits with periods of 10, 8, or 6.
2. The M port includes chattering exclusion circuits that operate for halt mode clear request signals.
These circuits exclude chattering for periods of 10, 8, or 6 when three of the ports are at the low level and a
signal change occurs on the remaining port.

Note
Use of the hold
transistor
(low level hold
transistor)
Hold transistor unused
(open)
This option can be specified individually for
each pin in S1 to S4 and M1 to M4.
When use of the hold transistor is selected:
This transistor is used to reduce the current
drain in the pull-up or pull-down resistor
when, for example, a push-button switch is
used for S1 or a slide switch is used for S2.
When the input open specifications are
used, this transistor turns the resistor on
prior to reading the input value and then
turns the resistor off after the input value is
read. If the input is floating when read, the
low-level input hold transistor will operate
and hold that level.
When the hold transistor is unused:
The pull-down transistor can be used as a
pull-down resistor.
The pull-down transistor can be turned on
and off under program control.
The pull-down resistor can be used in the
on state without change.
Select the unused option if the input is
connected to an external control signal line
that will never go to the floating state.
On reset
— The resistor will be in the on state during
the reset period.
— The resistor will keep up the on state
when reset is cleared.

LCD drive
CMOS output port
P-channel open-drain
output port
Used as LCD segment drive pins
The LCD drive type is specified independently.
The LCD drive type is common to all LCD drive pins and can be selected from the following set:
static, 1/2 bias—1/2 duty, 1/2 bias—1/3 duty, 1/2 bias—1/4 duty, 1/3 bias—1/3 duty, or 1/3 bias—1/4 duty.
General-purpose CMOS output ports
General-purpose p-channel open-drain output ports
This option can be specified for three specific ports using PLA option specification.
Available ports...Pads 64 to 66 (pins 34 to 36)
