MB90540/545 Series
11
75
P96
D
General I/O port. This function is enabled when CAN1 disables the
output.
TX1
TX Output pin for CAN1. This function is enabled when CAN1 en-
ables the output (only MB90540 series).
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 (only MB90540 se-
ries).
78
PA0
D
General I/O port. This function is always enabled.
34
AV
CC
Power supply
Power supply for the A/D Converter. This power supply must be
turned on or off while a voltage higher than or equal to AVcc is ap-
plied to Vcc.
37
AV
SS
Power supply Power supply for the A/D Converter.
35
AVRH
Power supply
External reference voltage input 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 AVcc.
36
AVRL
Power supply External reference voltage input for the A/D Converter.
49

MD0
MD1
C
Input pins for specifying the operating mode. The pins must be di-
rectly connected to Vcc or Vss.
51
MD2
F
Input pin for specifying the operating mode. The pin must be directly
connected to Vcc 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.
