23.1.4.9
23.1.4.10 STATE_ERRPAS Bit
23.1.4.11 STATE_BUSOFF Bit
The STATE_BUSERROR bit becomes 1 when a CAN communication error is detected.
The STATE_BUSERROR bit becomes 0 when transmit and receive operations are successfully completed
(regardless of whether a receive message has been stored in the message slot).
NOTE:
The STATE_ERRPAS bit becomes 1 when the value of the CiTEC or CiREC register (i = 0, 1) exceeds 127
which results in the CAN module to be placed in an error-passive state.
The STATE_ERRPAS bit becomes 0 when the CAN module exits an error-passive state to enter another error
state.
The STATE_ERRPAS bit becomes 0 when both the RESET1 and RESET0 bits are set to 1 (CAN module is
reset).
The STATE_BUSOFF bit becomes 1 when the value of the CiTEC register exceeds 255 which results in the
CAN module to be placed in a bus-off state.
The STATE_BUSOFF bit becomes 0 when the CAN module exits a bus-off state to enter an error-active state.
The STATE_BUSOFF bit becomes 0 when both the RESET1 and RESET0 bits are set to 1 (CAN module is
reset).
1. When the STATE_BUSERROR bit is 1, the STATE_BUSERROR bit remains unchanged even if both the
RESET1 and RESET0 bits are set to 1 (CAN module is reset).
