TEC7:TEC0: Transmit Error Counter bits
This register contains a value which is derived from the rate at which errors occur. When the
error count overflows, the bus-off state occurs. When the bus has 128 occurrences of
11 consecutive recessive bits, the counter value is cleared.
Unimplemented: Read as ‘0’
TXRTR: Transmission Frame Remote Transmission Request bit
1 = Transmitted message will have TXRTR bit set
0 = Transmitted message will have TXRTR bit cleared
Unimplemented: Read as ‘0’
