2.2 Description of Pin Functions
2.2.1 P12, P13 (port 1)
I/O. P13 can be selected to function as pins, using port function register 1 (PF1) (see Figure 4-19).
(1) Port mode
(2) Control mode
2.2.2 P20 to P25 (port 2)
controller/driver, 10-bit successive approximation type A/D converter analog input ( PD78F041x only). Either I/O port
function or segment signal output function can be selected using port function register 2 (PF2).
(1) Port mode
(2) Control mode
P12 and P13 function as a 2-bit I/O port. These pins also function as pins for key interrupt and serial interface data
The following operation modes can be specified in 1-bit units.
P20 to P25 function as a 6-bit I/O port. These pins also function as pins for segment signal output pins for the LCD
The following operation modes can be specified in 1-bit units.
P12 and P13 function as a 2-bit I/O port. P12 and P13 can be set to input or output port in 1-bit units using port
mode register 1 (PM1). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 1
(PU1).
P12 and P13 function as key interrupt and serial interface data I/O.
(a) KR3, KR4
(b) RxD0, RxD6
(c) TxD0, TxD6
P20 to P25 function as a 6-bit I/O port. P20 to P25 can be set to input or output port in 1-bit units using port
mode register 2 (PM2).
P20 to P25 function as segment signal output for the LCD controller/driver and 10-bit successive approximation
type A/D converter analog input ( PD78F041x only).
(a) SEG16 to SEG21
(b) ANI0 to ANI5 ( PD78F041x only)
Caution P20 to P25 are set in the digital input mode after release of reset.
These are key interrupt input pins.
These are the serial data input pins of the asynchronous serial interface.
These are the serial data output pins of the asynchronous serial interface.
These pins are the segment signal output pins for the LCD controller/driver.
These are 10-bit successive approximation type A/D converter analog input pins. When using these pins as
analog input pins, see (5)
successive approximation type A/D Converter.
ANI0/SEG21/P20 to ANI5/SEG16/P25 pins in 12.6
