receives a valid EOF symbol while operating in wait mode, then the
BDLC also will generate a CPU interrupt request which wakes up the
BDLC and the CPU. See
This power-conserving mode is entered automatically from run mode
whenever the CPU executes a STOP instruction or if the CPU executes
a WAIT instruction and the WCM bit in the BCR1 register is set
previously.
In this mode, the BDLC internal clocks are stopped but the physical
interface circuitry is placed in a low-power mode and awaits network
activity. If network activity is sensed, then a CPU interrupt request will be
generated, restarting the BDLC internal clocks. See
When a bus fault has been detected, the digital loopback mode is used
to determine if the fault condition is caused by failure in the node’s
internal circuits or elsewhere in the network, including the node’s analog
physical interface. In this mode, the transmit digital output pin (BDTxD)
and the receive digital input pin (BDRxD) of the digital interface are
disconnected from the analog physical interface and tied together to
allow the digital portion of the BDLC to transmit and receive its own
messages without driving the J1850 bus.
Analog loopback is used to determine if a bus fault has been caused by
a failure in the node’s off-chip analog transceiver or elsewhere in the
network. The BCLD analog loopback mode does not modify the digital
transmit or receive functions of the BDLC. It does, however, ensure that
once analog loopback mode is exited, the BDLC will wait for an idle bus
condition before participation in network communication resumes. If the
off-chip analog transceiver has a loopback mode, it usually causes the
input to the output drive stage to be looped back into the receiver,
allowing the node to receive messages it has transmitted without driving
the J1850 bus. In this mode, the output to the J1850 bus is typically high
