PA6
L
This is a general purpose I/O port.
SDA
This pin is also used as the data I/O pin for the I
2
C interface. This
function is valid when the I
2
C interface is enabled for operation. While
the I
2
C interface is operating, this port should be set to the input level
(DDRA: bit6 = 0).
71
PA7
L
This is a general purpose I/O port.
SCL
This pin is also used as the clock I/O pin for the I
2
C interface. This
function is valid when the I
2
C interface is enabled for operation. While
the I
2
C interface is operating, this port should be set to the input level
(DDRA: bit7 = 0).
72,
75 to 79
PB0,
PB1 to PB5
E
These are general-purpose I/O ports.
IRQ0,
IRQ1 to IRQ5
These pins are also the external interrupt input pins. IRQ0, 1 are en-
abled for both rising and falling edge detection, and therefore cannot
be used for recovery from STOP status for MB90V570, MB90F574,
MB90573 and MB90574. However, IRQ0, 1 can be used for recovery
from STOP status for MB90V570A, MB90F574A and MB90574C.
80
PB6
E
This is a general purpose I/O port.
ADTG
This is also the A/D converter external trigger input pin. While the A/D
converter is in input operation, this input signal is in continuous use,
and therefore the output function should only be used when needed.
81
PB7
E
This is a general purpose I/O port.
82 to 85
PC0 to PC3
E
These are general purpose I/O ports.

These are power supply (0V) input pins.
42
AV
CC
H
This is the analog macro (D/A, A/D etc.) Vcc power supply input pin.
43
AVRH
J
This is the A/D converter Vref+ input pin. The input voltage should not
exceed Vcc.
44
AVRL
H
This is the A/D converter Vref- input pin. The input voltage should not
less than Vss.
45
AV

H
This is the analog macro (D/A, A/D etc.) Vss power supply input pin.
38

This is the D/A converter Vref input pin. The input voltage should not
exceed Vcc.
39
DV
SS
H
This is the D/A converter GND power supply pin. It should be set to
Vss equivalent potential.
