115
DACK0/PL1
F
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
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.
116
DEOP0/PL2
F
DMA external transfer end output
This function is enabled when the end of DMAC external transfer is al-
lowed to be output.
117
DREQ1/PL3
F
DMA external transfer request input
Since this input is used more or less continuously when selected as a
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.
118
DACK1/PL4
F
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
tance is allowed to be output.
This pin is available as a port when DMAC transfer request acceptance
output is not allowed.
119
DEOP1/PL5
F
DMA external transfer end output
This function is enabled when the end of DMAC external transfer is al-
lowed to be output.
120
DREQ2/PL6
F
DMA external transfer request input
Since this input is used more or less continuously when selected as a
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.
121
DACK2/PL7
F
DMA external transfer request acceptance output
This function is enabled when the DMAC external transfer request accep-
tance is allowed to be output.
This pin is available as a port when DMAC transfer request acceptance
output is not allowed.
123
124
125
DA2
DA1
DA0
D/A converter output
This function is enabled when D/A converter output is allowed.
126
DAVS
Power supply pin for the D/A converter
127
DAVC
Power supply pin for the D/A converter
128
AVCC
Vcc power supply for the A/D converter
129
AVRH
A/D converter reference voltage (high potential side)
Be sure to turn on/off this pin with potential higher than AVRH applied to
VCC.
130
AVRL
A/D converter reference voltage (low potential side)
131
AVSS
VSS power supply for the A/D converter
