Description

MSCAN Receiver Flag Register

Fields

RXF

Receive Buffer Full Flag

0 (0): No new message available within the RxFG.

1 (1): The receiver FIFO is not empty. A new message is available in the RxFG.
OVRIF

Overrun Interrupt Flag

0 (0): No data overrun condition.

1 (1): A data overrun detected.
TSTAT

Transmitter Status

0 (00): TxOK: 0<=transmit error counter<96

1 (01): TxWRN: 96<=transmit error counter<128

2 (10): TxERR: 128<=transmit error counter<256

3 (11): Bus-off: 256<=transmit error counter
RSTAT

Receiver Status

0 (00): RxOK: 0<=receive error counter<96

1 (01): RxWRN: 96<=receive error counter<128

2 (10): RxERR: 128<=receive error counter

3 (11): Bus-off: 256<=transmit error counter (Redundant Information for the most critical CAN bus status which is “bus-off”. This only occurs if the Tx error counter exceeds a number of 255 errors. Bus-off affects the receiver state. As soon as the transmitter leaves its bus-off state the receiver state skips to RxOK too. Refer also to TSTAT[1:0] coding in this register. )
CSCIF

CAN Status Change Interrupt Flag

0 (0): No change in CAN bus status occurred since last interrupt.

1 (1): MSCAN changed current CAN bus status.
WUPIF

Wake-Up Interrupt Flag

0 (0): No wakeup activity observed while in sleep mode.

1 (1): MSCAN detected activity on the CAN bus and requested wakeup.
