CAN Sleep Mode
The 33742 offers two CAN Sleep modes:
Sleep mode with CAN wake-up enable: detection of
incoming CAN message and SBC wake-up.
Sleep mode with CAN wake-up disable: no detection of
incoming CAN message.
The CAN Sleep mode is done via the CAN SPI register.
In CAN Sleep mode (with wake-up enable or disable), the
CAN interface is internally supplied from the V
SUP
terminal. The
voltage at V2 terminal can be either 5.0 V or turned off. When
the CAN is in Sleep mode, the current sourced from V2 is
extremely low. In most cases the V2 voltage is off; however, the
CAN can be placed into Sleep mode even with 5.0 V applied on
V2.
In CAN Sleep mode, the CANH and CANL drivers are
disabled, and the receiver is also disabled. CANH and CANL
are high ohmic termination to ground.
CAN Signals in TXRX and Sleep Modes
When the CAN interface is set back into TXRX mode by an
SPI command, CAN H and CANL are set in recessive level.
This is illustrated in
Figure 18
