Function description
DMA external transfer request input
This pin is always in use when the pin is selected for a
DMA controller transfer source. Stop port output in
advance unless the resulting processing is intentional.
Can be used as a port when the pin is not used as
DMA transfer request input.
DMA external transfer request acceptance output
Effective when external transfer request acceptance
output specification of the DMA controller is enabled.
Can be used as a port when external transfer request
acceptance output specification of the DMA controller
is disabled.
D/A converter output
Effective when D/A converter output specification is
enabled.
Power supply pin of D/A converter
Power supply pin of D/A converter
V power supply for A/D converter
CC
A/D converter reference voltage (high potential side)
Be sure to turn on or off this pin when a potential of
AVRH or higher is applied to V
A/D converter reference voltage (low potential side)
V power supply for A/D converter
SS
A/D converter analog input
Effective when the AIC register specifies analog input.
Can be used as a port when A/D converter analog
input is not used.
Always connect the pin to the V
Oscillation pins for low-speed clock frequency (32 kHz)
Power supply of digital circuit
Be sure to connect the power supply to all V
.
