Embedded Target for Motorola MPC555

Description

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 Table 5-4.

Refer to section 16, "CAN 2.0B Controller Module," in the MPC555 Users Manual for further information.

Table 5-4: 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.
