Function
115
PL1/DACK0
F
DMA external transfer request acceptance output
This function is activated when the DMAC external transfer request ac-
ceptance 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
PL2/DEOP0
F
DMA external transfer end output
This function is activated when the end of DMAC external transfer is al-
lowed to be output.
This pin is available as a port when DMA external transfer end output is
disabled.
117
PL3/DREQ1
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
PL4/DACK1
F
DMA external transfer request acceptance output
This function is activated when the DMAC external transfer request ac-
ceptance is allowed to be output.
This pin is available as a port when DMAC transfer request acceptance
output is not allowed.
119
PL5/DEOP1
F
DMA external transfer end output
This function is activated when the end of DMAC external transfer is al-
lowed to be output.
This pin is available as a port when DMA external transfer end output is
disabled.
120
PL6/DREQ2
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
PL7/DACK2
F
DMA external transfer request acceptance output
This function is activated when the DMAC external transfer request ac-
ceptance 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 activated 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
