P40 functions as a 1-bit I/O port. These pins also function as pins for key interrupt input and power supply voltage
The following operation modes can be specified in 1-bit units.
P100 and P101 function as a 2-bit I/O port. These pins also function as segment signal output pins for the LCD
P112 and P113 function as a 2-bit I/O port. These pins also function as pins for segment signal output pins for the
P40 functions as a 1-bit I/O port. P40 can be set to input port or output port in 1-bit units using port mode register
4 (PM4). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 4 (PU4).
P40 functions as key interrupt input and power supply voltage for driving the LCD.
(a) KR0
(b) V
P100 and P101 function as a 2-bit I/O port. P100 and P101 can be set to input or output port in 1-bit units using
port mode register 10 (PM10). Use of an on-chip pull-up resistor can be specified by pull-up resistor option
register 10 (PU10).
P100 and P101 function as segment signal output for the LCD controller/driver.
(a) SEG4, SEG5
P112 and P113 function as a 2-bit I/O port. P112 and P113 can be set to input or output port in 1-bit units using
port mode register 11 (PM11). Use of an on-chip pull-up resistor can be specified by pull-up resistor option
register 11 (PU11).
P112 and P113 function as segment signal output for the LCD controller/driver and serial interface data I/O.
This is the key interrupt input pins.
This is the power supply voltage pins for driving the LCD.
These pins are the segment signal output pins for the LCD controller/driver.
