Pin name
Circuit type
Function
PA6
SDA
L
This is a general purpose I/O port.
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).
This is a general purpose I/O port.
71
PA7
SCL
L
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).
These are general-purpose I/O ports.

IRQ0,
IRQ1 to IRQ5
E
These pins are also the external interrupt input pins. IRQ0, 1 are
enabled 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.
This is a general purpose I/O port.
80
PB6
ADTG
E
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.
This is a general purpose I/O port.

AVRH
This is the analog macro (D/A, A/D etc.) Vcc power supply input pin.
This is the A/D converter Vref+ input pin. The input voltage should not
exceed Vcc.
This is the A/D converter Vref-input pin. The input voltage should not
less than Vss.
This is the analog macro (D/A, A/D etc.) Vss power supply input pin.
