Alternate Function Function
P00 7-1-2 I/O Input port SO00/TXD0/INTP1 Port 0.
8-bit I/O port.
Input/output can be specified in 1-bit units.
Use of an on-chip pull-up resistor can be
specified by a software setting at input port.
Output of P00, P01, P06, and P07 can be set to
N-ch open-drain output (V
DD tolerance).
P01 to P07 can be set to analog input

Port 4
2-bit I/O port.
Input/output can be specified in 1-bit units.
Use of an on-chip pull-up resistor can be
specified by a software setting at input port.
P41 TI03/INTP2
P121 2-2-1 Input Input port X1/(INTP3) Port 12
3-bit input port.
For P125, use of an on-chip pull-up resistor can
be specified by a software setting.
P125 is also used for the input pin for external
reset (RESET).
To use the pin for external reset, set the
PORTSELB bit in the option byte (000C1H) to
1.
P122 X2/EXCLK/(INTP2)
P125 3-1-1 KR1/RESET
P137 2-1-2 Input Input port TI00/INTP0 Port 13
1-bit input only port.
Note Setting digital or analog to each pin can be done in the port mode control register 0 (PMC0) (can be set in 1-bit
units).
Remark Functions in parentheses in the above figure can be assigned via settings in the peripheral I/O redirection
register (PIOR). Refer to Figure 4-6 Format of Peripheral I/O Redirection Register (PIOR).
