Description
The VREF pin supplies the reference voltage to the A/D converter
and D/A converter.
Analog input pins for the A/D converter.
External trigger input pin for the A/D converter.
Extended analog input pin for the A/D converter or output pin in
external op-amp connection mode.
Extended analog input pin for the A/D converter.
Output pins for the D/A converter.
8-bit CMOS I/O ports. The Port Pi Direction Register determines
if each pin is used as an input port or an output port. The Pull-up
Control Register determines if the input ports, divided into groups
of four, are pulled up or not.
These 8-bit I/O ports are functionally equivalent to P0.
(P7_0 and P7_1 are N-channel open drain output.)
These I/O ports are functionally equivalent to P0.
Shares the pin with NMI. Input port to read NMI pin level.
Key input interrupt input pins
NOTE:
1. P0 to P5 function as bus control pins and cannot be used as I/O ports. P1_0 to P1_7 can be used as I/O ports
when using with 8-bit external bus width only.
