CAN INTERRUPT REGISTERS
bit 7
IRXIF: CAN Invalid Received Message Interrupt Flag bit
1 = An invalid message has occurred on the CAN bus
0 = No invalid message on CAN bus
WAKIF: CAN bus Activity Wake-up Interrupt Flag bit
1 = Activity on CAN bus has occurred
0 = No activity on CAN bus
ERRIF: CAN bus Error Interrupt Flag bit
1 = An error has occurred in the CAN module (multiple sources)
0 = No CAN module errors
When CAN is in Mode 0:
TXB2IF: CAN Transmit Buffer 2 Interrupt Flag bit
1 = Transmit Buffer 2 has completed transmission of a message and may be reloaded
0 = Transmit Buffer 2 has not completed transmission of a message
When CAN is in Mode 1 or 2:
TXBnIF: Any Transmit Buffer Interrupt Flag bit
1 = One or more transmit buffers have completed transmission of a message and may be reloaded
0 = No transmit buffer is ready for reload
TXB1IF: CAN Transmit Buffer 1 Interrupt Flag bit
1 = Transmit Buffer 1 has completed transmission of a message and may be reloaded
0 = Transmit Buffer 1 has not completed transmission of a message
TXB0IF: CAN Transmit Buffer 0 Interrupt Flag bit
1 = Transmit Buffer 0 has completed transmission of a message and may be reloaded
0 = Transmit Buffer 0 has not completed transmission of a message
When CAN is in Mode 0:
RXB1IF: CAN Receive Buffer 1 Interrupt Flag bit
1 = Receive Buffer 1 has received a new message
0 = Receive Buffer 1 has not received a new message
When CAN is in Mode 1 or 2:
RXBnIF: Any Receive Buffer Interrupt Flag bit
1 = One or more receive buffers has received a new message
0 = No receive buffer has received a new message
When CAN is in Mode 0:
RXB0IF: CAN Receive Buffer 0 Interrupt Flag bit
1 = Receive Buffer 0 has received a new message
0 = Receive Buffer 0 has not received a new message
When CAN is in Mode 1:
Unimplemented: Read as ‘0’
When CAN is in Mode 2:
FIFOWMIF: FIFO Watermark Interrupt Flag bit
1 = FIFO high watermark is reached
0 = FIFO high watermark is not reached
