70
PA6
L
This is a general purpose I/O port.
SDA
This pin is also used as the data I/O pin for the I2C interface. This
function is valid when the I2C interface is enabled for operation. While
the I2C 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 I2C interface. This
function is valid when the I2C interface is enabled for operation. While
the I2C 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.
8,54,94
VCC
Power
supply
These are power supply (5V) input pins.
33,63,
91,119
VSS
Power
supply
These are power supply (0V) input pins.
42
AVCC
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
AVSS
H
This is the analog macro (D/A, A/D etc.) Vss power supply input pin.
38
DVCC
H
This is the D/A converter Vref input pin. The input voltage should not
exceed Vcc.
39
DVSS
H
This is the D/A converter GND power supply pin. It should be set to
Vss equivalent potential.
