6.7.1.2 Lowpower/Off modes
and
In CAN Active mode, the transceiver can transmit and receive data via the CANH and
CANL pins. The differential receiver converts the analog data on the bus lines into digital
data which is output on pin RXDC. The transmitter converts digital data generated by a
CAN controller, and input on pin TXDC, to signals suitable for transmission over the bus
lines.
The CAN transceiver will be in Lowpower mode with bus wake-up detection enabled if bit
STBCC = 1 (see
and CANL in Lowpower mode.
When the SBC is in Standby mode or Sleep mode (MC = 00 or 01), the CAN transceiver
will be in Off mode if bit STBCC = 0. The CAN transceiver is powered down completely in
Off mode to minimize quiescent current consumption.
A filter at the receiver input prevents unwanted wake-up events occurring due to
automotive transients or EMI.
A recessive-dominant-recessive-dominant sequence must occur on the CAN bus within
the wake-up timeout time (t
