VCC1
CEC I/O (N-channel open drain output).
Reference voltage input for the A/D and D/A converters.
Analog input.
External trigger input.
Extended analog input.
Output pin the D/A converter.
VCC2
8-bit CMOS I/O ports. A direction register determines
whether each pin is used as an input port or an output
port. A pull-up resistor may be enabled or disabled for
input ports in 4-bit units.
VCC1
VCC1
8-bit I/O ports having equivalent functions to P0. However,
P7_0, P7_1, and P8_5 are N-channel open drain output
ports. No pull-up resistor is provided. P8_5 is an input port
for verifying the NMI pin level and shares a pin with NMI.
I/O ports having equivalent functions to P0.
