2.2 Pin Functions
2.2.1 P00 to P03 (Port 0)
register 0 (PM0). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 0 (PU0).
2.2.2 P20 to P23 (Port 2)
analog signals to the A/D converter. These pins can be set to the following operation modes in 1-bit units.
2.2.3 P30 to P34 (Port 3)
input/output a timer signal, and input an external interrupt request signal.

P34 pin by using external resistor.
P00 to P03 function as a 4-bit I/O port. P00 to P03 can be set to input or output in 1-bit units using port mode
P20 to P23 constitute a 4-bit I/O port, port 2. In addition to I/O port pins, these pins also have a function to input
(1) Port mode
(2) Control mode
P30 to P33 constitute a 4-bit I/O port, port 3. In addition to I/O port pins, P30 and p31 also have functions to
P34 is a 1-bit input-only port. This pin is also used as a RESET pin, and when the power is turned on, this is the
For settings of alternate function, refer to CHAPTER 18 OPTION BYTE. When using P34 as input port, pull up the
P30 to P34 can be set to the following operation modes in 1-bit units.
(1) Port mode
(2) Control mode
P20 to P23 function as a 4-bit I/O port. Each bit of this port can be set to the input or output mode by using
port mode register 2 (PM2). In addition, an on-chip pull-up resistor can be connected to the port by using pull-
up resistor option register 2 (PU2).
P20 to P23 function as the analog input pins (ANI0 to ANI3) of the A/D converter. When using these pins as
analog input pins, refer to 10.6 Cautions for A/D converter (5) ANI0/P20 to ANI3/P23.
P30 to P33 function as a 4-bit I/O port. Each bit of this port can be set to the input or output mode by using
port mode register 3 (PM3). In addition, an on-chip pull-up resistor can be connected to the port by using pull-
up resistor option register 3 (PU3).
P34 functions as a 1-bit input-only port.
P30 and P31 function to input/output signals to/from internal timers, and to input an external interrupt request
signal.
(a) INTP0 and INTP2
(b) TI000
(c) TI010
These are external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This pin inputs an external count clock to 16-bit timer/event counter 00, or a capture trigger signal to the
capture registers (CR000 and CR010) of 16-bit timer/event counter 00.
This pin inputs a capture trigger signal to the capture register (CR000) of 16-bit timer/event counter 00.
