Function
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
F tance is allowed to be output.
This pin is available as a port when the DMAC transfer request accep-
tance is not allowed to be output.
DMA external transfer end output
F This function is enabled when the end of DMAC external transfer is al-
lowed to be output.
DMA external transfer request input
Since this input is used more or less continuously when selected as a
F
DMAC transfer factor, output by the port needs to be stopped except when
it is performed deliberately.
This pin is available as a port when DMA external transfer request input is
not in use.
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
F tance is allowed to be output.
This pin is available as a port when DMAC transfer request acceptance
output is not allowed.
DMA external transfer end output
F This function is enabled when the end of DMAC external transfer is al-
lowed to be output.
DMA external transfer request input
Since this input is used more or less continuously when selected as a
F
DMAC transfer factor, output by the port needs to be stopped except when
it is performed deliberately.
This pin is available as a port when DMA external transfer request input is
not in use.
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
F tance is allowed to be output.
This pin is available as a port when DMAC transfer request acceptance
output is not allowed.
D/A converter output
This function is enabled when D/A converter output is allowed.
Power supply pin for the D/A converter
Power supply pin for the D/A converter
Vcc power supply for the A/D converter
A/D converter reference voltage (high potential side)
Be sure to turn on/off this pin with potential higher than AVRH applied to
Vcc.
A/D converter reference voltage (low potential side)
Vss power supply for the A/D converter
