This register reflects the status of the msCAN12 transmit error counter.
The register is read only.
Both error counters must only be read when in SLEEP or SOFT_RESET
mode.
On reception each message is written into the background receive
buffer. The CPU is only signalled to read the message however, if it
passes the criteria in the identifier acceptance and identifier mask
registers (accepted); otherwise, the message is overwritten by the next
message (dropped).
The acceptance registers of the msCAN12 are applied on the IDR0 to
IDR3 registers of incoming messages in a bit by bit manner.
For extended identifiers all four acceptance and mask registers are
applied. For standard identifiers only the first two (CIDMR0/1 and
CIDAR0/1) are applied.
