MSCAN08 Controller (MSCAN08)
12.13.11 MSCAN08 Transmit Error Counter
This read-only register reflects the status of the MSCAN08 transmit error counter.
12.13.12 MSCAN08 Identifier Acceptance Registers
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 will be overwritten by the next message (dropped).
The acceptance registers of the MSCAN08 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/CIDMR1 and CIDAR0/CIDAR1) are applied.
