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.

Function
75
P96
D
General I/O port. This function is enabled when CAN1 disables out-
put.
TX1
TX output pin for CAN1. This function is enabled when CAN1 en-
ables output.
76
P97
D
General I/O port. This function is always enabled.
RX1
RX input pin for CAN1 interface. When the CAN function is used,
output from the other functions must be stopped.
78
PA0
D
General I/O port. This function is always enabled.
INT3
External interrupt request input pin for INT2. Set the corresponding
DDR register to input if this function is used.
34
AV
CC
Power supply
Power supply pin for the A/D Converter. This power supply must be
turned on or off while a voltage higher than or equal to AV
CC
is ap-
plied to V
CC
.
37
AV
SS
Power supply Dedicated ground pin for the A/D Converter
35
AVRH
Power supply
External reference voltage pin for the A/D Converter. This power
supply must be turned on or off while a voltage higher than or equal
to AVRH is applied to AV
CC
.
36
AVRL
Power supply External reference voltage pin for the A/D Converter
49
to 50
MD0
to MD1
C
Input pins for specifying the operating mode. The pins must be di-
rectly connected to V
CC
or Vss.
51
MD2
F
Input pin for specifying the operating mode. The pin must be directly
connected to V
CC
or Vss.
27
C
This is the power supply stabilization capacitor pin. It should be con-
nected externally to an 0.1
μ
F ceramic capacitor.
