Target Support Package FM5/ MPC555 Driver Library/ CAN 2.0B Controller Module
The TouCAN Fault Confinement State block provides an indicator for the state of the selected TouCAN module. The block obtains and outputs a field of two bits from the TouCAN module's Error and Status (ESTAT) register. The possible states are shown in the table below.
Refer to section 16, "CAN 2.0B Controller Module," in the MPC555 User's Manual for further information.
FCS State Values
State | Value | Description |
|---|---|---|
Error Active | 00 | Normal operation |
Error Passive | 01 | Listening only mode. The device cannot transmit. |
Bus Off | 1x | The device is not allowed to transmit or receive and is effectively cut off from the bus. |
Select TouCAN module A, B or C. Note that the MPC555 only has modules A and B. MPC56x (561-6) also have module C. An error will be thrown if you select C and your target processor does not support this.
