Freescale Semiconductor /SKEAZ1284 /MSCAN /CANRIER

Receiver Full Interrupt Enable

0 (0): No interrupt request is generated from this event.

1 (1): A receive buffer full (successful message reception) event causes a receiver interrupt request.

Overrun Interrupt Enable

0 (0): No interrupt request is generated from this event.

1 (1): An overrun event causes an error interrupt request.

Transmitter Status Change Enable

0 (00): Do not generate any CSCIF interrupt caused by transmitter state changes.

1 (01): Generate CSCIF interrupt only if the transmitter enters or leaves “bus-off” state. Discard other transmitter state changes for generating CSCIF interrupt.

2 (10): Generate CSCIF interrupt only if the transmitter enters or leaves “TxErr” or “bus-off” state. Discard other transmitter state changes for generating CSCIF interrupt.

3 (11): Generate CSCIF interrupt on all state changes.

Receiver Status Change Enable

0 (00): Do not generate any CSCIF interrupt caused by receiver state changes.

1 (01): Generate CSCIF interrupt only if the receiver enters or leaves “bus-off” state. Discard other receiver state changes for generating CSCIF interrupt.

2 (10): Generate CSCIF interrupt only if the receiver enters or leaves “RxErr” or "bus-off"Bus-off state is only defined for transmitters by the CAN standard (see Bosch CAN 2.0A/B protocol specification). Because the only possible state change for the transmitter from bus-off to TxOK also forces the receiver to skip its current state to RxOK, the coding of the RXSTAT[1:0] flags define an additional bus-off state for the receiver state. Discard other receiver state changes for generating CSCIF interrupt.

3 (11): Generate CSCIF interrupt on all state changes.

CAN Status Change Interrupt Enable

0 (0): No interrupt request is generated from this event.

1 (1): A CAN Status Change event causes an error interrupt request.

WakeUp Interrupt Enable

0 (0): No interrupt request is generated from this event.

1 (1): A wake-up event causes a Wake-Up interrupt request.
