These pins are segment signal output pins for the LCD controller/driver.
These pins are common signal output pins for the LCD controller/driver.
These pins are power supply voltage pins to drive the LCD.
This pin supplies power to drive the LCD.
This pin is the A/D converter reference voltage pin. Connect it to V
This pin is the A/D converter analog circuit power supply pin. Always keep it at the same potential as the V
Port mode
In this port mode, P80 to P87 function as an 8-bit I/O port. These pins can be set to input or output mode in
1-bit units by using port mode register 8 (PM8). When used as an input port pins, an on-chip pull-up resistor
can be used by setting pull-up resistor option register 2 (PU2).
Control mode
In this mode, P80 to P87 function as segment signal output pins (S20 to S27) for the LCD controller/driver.
Port mode
In this mode, P90 to P93 function as a 4-bit I/O port. These pins can be set to input or output mode in 1-bit
units by using port mode register 9 (PM9). When used as input port pins, an on-chip pull-up resistor can be
used by setting pull-up resistor option register 2 (PU2).
Control mode
In this mode, P90 to P93 function as segment signal output pins (S16 to S19) for the LCD controller/driver.
