Section 19 Controller Area Network (RCAN-ET)
• Normal Mode
• Listen-Only Mode:
• Self Test Mode 1
• Self Test Mode 2
• Write Error Counter
• Error Passive mode
Note: the REC will not be modified by implementing this Mode. However, once running in
When message error occurs, IRR13 is set in all test modes.

RCAN-ET operates in the normal mode.
ISO-11898 requires this mode for baud rate detection. The Error Counters are cleared and
disabled so that the TEC/REC does not increase the values, and the CTx Output is disabled so
that RCAN-ET does not generate error frames or acknowledgment bits. IRR13 is set when a
message error occurs.
RCAN-ET generates its own Acknowledge bit, and can store its own messages into a reception
mailbox (if required). The CRx/CTx pins must be connected to the CAN bus.
RCAN-ET generates its own Acknowledge bit, and can store its own messages into a reception
mailbox (if required). The CRx/CTx pins do not need to be connected to the CAN bus or any
external devices, as the internal CTx is looped back to the internal CRx. CTx pin outputs only
recessive bits and CRx pin is disabled.
TEC/REC can be written in this mode. RCAN-ET can be forced to become an Error Passive
mode by writing a value greater than 127 into the Error Counters. The value written into TEC
is used to write into REC, so only the same value can be set to these registers. Similarly,
RCAN-ET can be forced to become an Error Warning by writing a value greater than 95 into
them.
RCAN-ET needs to be in Halt Mode when writing into TEC/REC (MCR1 must be "1" when
writing to the Error Counter). Furthermore this test mode needs to be exited prior to leaving
Halt mode.Error Passive Mode: RCAN-ET can be forced to enter Error Passive mode.
Error Passive Mode, the REC will increase normally should errors be received. In this
Mode, RCAN-ET will enter BusOff if TEC reaches 256 (Dec). However when this mode
is used RCAN-ET will not be able to become Error Active. Consequently, at the end of the
Bus Off recovery sequence, RCAN-ET will move to Error Passive and not to Error Active
