Normal Mode:
Listen-Only Mode:
Self Test Mode 1:
Self Test Mode 2:
Write Error Counter: TEC/REC can be written in this mode. RCAN-TL1 can be forced to
Error Passive Mode:
When message error occurs, IRR13 is set in all test modes.
RCAN-TL1 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 CTxn (n = 0, 1) Output is disabled so that RCAN-TL1 does not
generate error frames or acknowledgment bits. IRR13 is set when a
message error occurs.
RCAN-TL1 generates its own Acknowledge bit, and can store its own
messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1)
pins must be connected to the CAN bus.
RCAN-TL1 generates its own Acknowledge bit, and can store its own
messages into a reception mailbox (if required). The CRxn/CTxn (n = 0, 1)
pins do not need to be connected to the CAN bus or any external devices,
as the internal CTxn (n = 0, 1) is looped back to the internal CRxn (n = 0,
1). CTxn (n = 0, 1) pin outputs only recessive bits and CRxn (n = 0, 1) pin
is disabled.
RCAN-TL1 can be forced to enter Error Passive mode.
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-TL1
can be forced to become an Error Warning by writing a value greater than
95 into them.
RCAN-TL1 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.
Note: The REC will not be modified by implementing this Mode.
However, once running in Error Passive Mode, the REC will increase
normally should errors be received. In this Mode, RCAN-TL1 will enter
BusOff if TEC reaches 256 (Dec). However when this mode is used
RCAN-TL1 will not be able to become Error Active. Consequently, at the
end of the Bus Off recovery sequence, RCAN-TL1 will move to Error
Passive and not to Error Active.
