These are 4-bit I/O ports. Besides serving as I/O ports, they function as an external interrupt input, and A/D
The following operating modes can be specified in 1-bit units.
These are 8-bit input-only ports. Besides serving as input ports, they function as an A/D converter analog input.
The following operating modes can be specified in 1-bit units.
These ports function as 4-bit I/O ports.
P00 to P03 can be specified as input or output ports in 1-bit units with port mode register 0 (PM0). On-chip pull-
up resistors can be used by setting pull-up resistor option register 0 (PU0).
These ports function as an external interrupt request input, and A/D converter external trigger input.
(a) INTP0 to INTP3
(b) ADTRG
These ports function as 8-bit input-only ports.
These ports function as A/D converter analog input pins (ANI0 to ANI7).
INTP0 to INTP3 are external interrupt request input pins which can specify valid edges (rising edge, falling
edge, and 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
bits 1, 2 (EGA00, EGA01) of A/D converter mode register (ADM0) and set interrupt mask
flag (PMK3) to 1.
