Function
General I/O port. This function is enabled when CAN1 disables out-
put.
D
TX output pin for CAN1. This function is enabled when CAN1 en-
ables output.
General I/O port. This function is always enabled.
D
RX input pin for CAN1 interface. When the CAN function is used,
output from the other functions must be stopped.
General I/O port. This function is always enabled.
D
External interrupt request input pin for INT2. Set the corresponding
DDR register to input if this function is used.
Power supply pin for the A/D Converter. This power supply must be
Power supply turned on or off while a voltage higher than or equal to AVCC is ap-
plied to VCC.
Power supply Dedicated ground pin for the A/D Converter
External reference voltage pin for the A/D Converter. This power
Power supply supply must be turned on or off while a voltage higher than or equal
to AVRH is applied to AVCC.
Power supply External reference voltage pin for the A/D Converter
C
Input pins for specifying the operating mode. The pins must be di-
rectly connected to VCC or Vss.
F
Input pin for specifying the operating mode. The pin must be directly
connected to VCC or Vss.
⎯
This is the power supply stabilization capacitor pin. It should be con-
nected externally to an 0.1 µF ceramic capacitor.
Power supply Voltage (5.0 V) input pin

■ INPUT LEVELS
The input level of ports P00 to P37 can be selected to be either TTL- or CMOS - level. The initial setting is TTL
- level. These settings are global for all P00 to P37, it is not possible to set different levels to each port.
The input level of ports P40 to PA0 can be selected to be either CMOS- or AUTOMOTIVE - level. The initial
setting is CMOS - level. This settings can be done for each port individually.
