CONTROLLER AREA NETWORK (bxCAN)

TRANSMIT ERROR COUNTER REG. (TECR)
Read Only
Reset Value: 00h
TEC[7:0] is the least significant byte of the 9-bit
Transmit Error Counter implementing part of the
fault confinement mechanism of the CAN protocol.
RECEIVE ERROR COUNTER REG. (RECR)
Page: 00h — Read Only
Reset Value: 00h
REC[7:0] is the Receive Error Counter implement-
ing part of the fault confinement mechanism of the
CAN protocol. In case of an error during reception,
this counter is incremented by 1 or by 8 depending
on the error condition as defined by the CAN stand-
ard. After every successful reception the counter is
decremented by 1 or reset to 120 if its value was
higher than 128. When the counter value exceeds
127, the CAN controller enters the error passive
state.
