NORMAL MODE
Normal mode is the mode for normal bi-directional CAN
communication. The receiver will convert the differential
analog bus signal on pins CANH and CANL into digital
data, available for output to pin RXD. The transmitter will
convert digital data on pin TXD into a differential analog
signal, available for output to the bus pins. The bus pins
are biased at 0.5VCC (via Ri(cm)). Pin INH is active, so
voltage regulators controlled by pin INH (see Fig.4) will be
active too.
PWON/LISTEN-ONLY MODE
In pwon/listen-only mode the transmitter of the transceiver
is disabled, effectively providing a transceiver listen-only
behaviour. The receiver will still convert the analog bus
signal on pins CANH and CANL into digital data, available
for output to pin RXD. As in normal mode the bus pins are
biased at 0.5VCC, and pin INH remains active.
STANDBY MODE
The standby mode is the first-level power saving mode of
the transceiver, offering reduced current consumption.
In standby mode the transceiver is not able to transmit or
receive data and the low-power receiver is activated to
monitor bus activity. The bus pins are biased at ground
level (via Ri(cm)). Pin INH is still active, so voltage
regulators controlled by this pin INH will be active too.
