Description
Test Mode
Enables/disables the test modes settable by TST[6:0].
When this bit is set, the following TST[6:0] become
effective.
0: HCAN2 is in normal mode
1: HCAN2 is in test mode
Write CAN Error Counters
Enables the TEC (Transmit Error Counter) and REC
(Receive Error Counter) to be writable. The same value
can only be written into the TEC/REC at the same time.
The maximum value that can be written into the TEC/REC
is D'255 (H'FF). This means that the HCAN2 cannot be
forced into the bus off state. Before writing into the
TEC/REC, HCAN2 needs to be put into Halt Mode, and
when writing into the TEC/REC, the TST7 (MCR15) needs
to be ‘1’. Only the same value can be set between
TEC/REC, and the value written into TEC is used to write
REC.
0: TEC/REC is not writable but read-only
1: TEC/REC is writable with the same value at the same
Force to Error Passive
Forces HCAN2 to become error passive. When this bit is
set, HCAN2 behaves as an error passive node, regardless
of the error counters.
0: State of HCAN2 depends on the error counters
1: HCAN2 behaves as an error passive node regardless of
time
the error counters
