30, 31
P75, P76
K
General-purpose I/O port
DA0
DA1
This pin serves as the D/A converter output pin.
The pin functions when enabled by the control status register.
32
AVCC
—
A/D converter power supply pin
33
AVRH
—
“H” reference power supply pin for the A/D converter
34
AVRL
—
“L” reference power supply pin for the A/D converter
35
AVSS
—
A/D converter power pin (GND)
36 to 39
P60 to P63
J
General-purpose I/O port
This port is enabled when the analog input enable register setting is
“port.”
AN0 to AN3
A/D converter analog input pins
These pins are enabled when the analog input enable register setting
is “analog input.”
40
VSS
—
Power pin (GND)
41 to 43
P64 to P66
J
General-purpose I/O port
This port is enabled when the analog input enable register setting is
“port.”
AN4 to AN6
A/D converter analog input pins
These pins are enabled when the analog input enable register setting
is “analog input.”
44
P67
J
General-purpose I/O port
This port is enabled when the analog input enable register setting is
“port.”
AN7
A/D converter analog input pin
This pin is enabled when the analog input enable register setting is
“analog input.”
CMP
Comparator input pin
45
P80
L*2
General-purpose I/O port
This port is always enabled.
INT0
External interrupt request input 0
Since this pin serves for interrupt request as required when external
interrupt is enabled, other outputs must be off unless used
intentionally.
46
P81
L*2
General-purpose I/O port
This port is always enabled.
INT1
External interrupt request input 1
Since this pin serves for interrupt request as required when external
interrupt is enabled, other outputs must be off unless used
intentionally.
47
MD0
C
Mode pin
This pin must be fixed to VCC or VSS.
48
MD1
C
Mode pin
This pin must be fixed to VCC or VSS.
