IE — Interrupt Enable
Determines whether the BDLC will generate CPU interrupt requests in the run mode. It does not affect
CPU interrupt requests when exiting the BDLC stop or BDLC wait modes.
0 = Disable interrupt requests from BDLC
1 = Enable interrupt requests from BDLC
WCM — Wait Clock Mode
Determines the operation of the BDLC during CPU wait mode
0 = Run BDLC internal clocks during CPU wait mode
1 = Stop BDLC internal clocks during CPU wait mode
Controls transmitter operations of the BDLC.
ALOOP — Analog Loopback Status
Sets the BDLC state machine to a known state after the off-chip analog transceiver has been put in loop
back mode.
0 = Off-chip analog transceiver has been taken out of analog loopback mode
1 = Off-chip analog transceiver has been put into analog loopback mode
DLOOP — Digital Loopback Mode
Determines the RxPD source and can isolate bus fault conditions. If a fault condition is detected on the
bus, RxPD can be disconnected from the analog transceiver’s receive output and connected to TxPD
to determine if the fault is in the digital block or elsewhere on the J1850 bus.
0 = RxPD is connected to the analog transceiver’s receive output. The BDLC is taken out of digital
loopback mode and can now drive and receive from the J1850 bus normally if ALOOP is not set.
1 = RxPD is connected to TxPD. The BDLC is now in digital loopback mode of operation. The an-
alog transceiver’s transmit input is still driven by TxPD.
