4.2.2 P10 to P17 (Port 1)
analog inputs.
(1) Port mode
(2) Control mode
4.2.3 P20 to P25 (Port 2)
serial interfaces CSI1 and UART0.
(1) Port mode
P00 to P03 function as a 4-bit I/O port. Besides serving as an I/O port, they also function as external interrupt
The following operating modes can be specified in 1-bit units.
P10 to P17 function as an 8-bit input-only port. Besides serving as an input port, they also function as A/D converter
The following operating modes can be specified in 1-bit units.
P20 to P25 function as a 6-bit I/O port. Besides serving as an I/O port, they function as data I/O and clock I/O for
The following operating modes can be specified in 1-bit units.
(a) INTP0 to INTP3
(b) ADTRG
These pins function as a 4-bit I/O port.
P00 to P03 can be specified as input or output in 1-bit units using port mode register 0 (PM0). On-chip pull-up
resistors can be connected by setting pull-up resistor option register 0 (PU0).
In this mode, these pins function as external interrupt request inputs and an A/D converter external trigger input.
These pins function as an 8-bit input-only port.
These pins function as A/D converter analog input pins (ANI0 to ANI7). When using these pins as analog input
pins, see (4) ANI0/P10 to ANI7/P17 in 13.6 Cautions for A/D Converter.
These pins function as a 6-bit I/O port. They can be specified as input or output in 1-bit units using port mode
register 2 (PM2). On-chip pull-up resistors can be connected by setting pull-up resistor option register 2 (PU2).
INTP0 to INTP3 are external interrupt request input pins for which the valid edge can be specified (rising
edge, falling edge, or both rising and falling edges).
A/D converter external trigger input pin.
Caution
When P03 is used as an A/D converter external trigger input, specify the valid edge by
using bits 1 and 2 (EGA00, EGA01) of the A/D converter mode register (ADM0) and set the
interrupt mask flag (PMK3) to 1.
