CONTROLLER AREA NETWORK (Cont’d)
– ERROR. The error management as described in
Figure 58. CAN Error State Diagram
the CAN protocol is completely handled by hard-
ware using 2 error counters which get increment-
ed or decremented according to the error
condition. Both of them may be read by the appli-
When 128 * 11 recessive bits occur:
- the BOFF bit gets cleared
- the TECR register gets cleared
- the RECR register gets cleared
ERROR ACTI VE
When TECR or RECR > 127, the EPSV bit gets set
the EPSV bit gets cleared
When TECR and RECR < 128,

cation to determine the stability of the network.
Moreover, as one of the node status bits (EPSV
or BOFF of the CSR register) changes, an inter-
rupt is generated if the SCIE bit is set in the ICR
Register. Refer to Figure 58.
ERROR PASSI VE
When TECR > 255 the BOFF bit gets set
and the EPSV bit gets cleared
