PIR REGISTERS (CONT’D)
Legend:
R = Readable bit
- n = Value at POR
IRXIF: Invalid Message Received Interrupt Flag bit
1 = An invalid message has occurred on the CAN bus
0 = An invalid message has not occurred on the CAN bus
WAKIF: Bus Activity Wake-up Interrupt Flag bit
1 = Activity on the CAN bus has occurred
0 = Activity on the CAN bus has not occurred
ERRIF: CAN Bus Error Interrupt Flag bit
1 = An error has occurred in the CAN module (multiple sources)
0 = An error has not occurred in the CAN module
TXB2IF: 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
TXB1IF: 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: 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
RXB1IF: 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
RXB0IF: 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
