Legend: HS = Hardware Settable bit C = Clearable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 IVMIF: Invalid Message Interrupt Flag bit
(1)
1 = Invalid message interrupt occurred
0 = No invalid message interrupt
bit 14 WAKIF: Bus Wake-up Activity Interrupt Flag bit
(1)
1 = Wake-up activity interrupt occurred
0 = No wake-up activity interrupt
bit 13 CERRIF: CAN Bus Error Interrupt Flag bit
(1)
1 = CAN bus error interrupt occurred
0 = No CAN bus error interrupt
bit 12 SERRIF: System Error Interrupt flag bit
(1)
1 = System error interrupt occurred
0 = No system error interrupt
bit 11 RXOVIF: Receive Buffer Overflow Interrupt Flag bit
1 = Receive buffer overflow interrupt occurred
0 = No receive buffer overflow interrupt
bit 10 TXATIF: Transmit Attempt Interrupt Flag bit
1 = Transmit attempt interrupt occurred
0 = No transmit attempt interrupt
bit 9-5 Unimplemented: Read as ‘0’
bit 4 TEFIF: Transmit Event FIFO Interrupt Flag bit
1 = Transmit event FIFO interrupt occurred
0 = No transmit event FIFO
bit 3 MODIF: CAN Mode Change Interrupt Flag bit
(1)
1 = CAN module mode change occurred (OPMOD<2:0> have changed to reflect REQOP<2:0>)
0 = No mode change occurred
bit 2 TBCIF: CAN Timer Overflow Interrupt Flag bit
(1)
1 = TBC has overflowed
0 = TBC has not overflow
bit 1 RXIF: Receive Object Interrupt Flag bit
1 = Receive object interrupt is pending
0 = No receive object interrupts are pending
bit 0 TXIF: Transmit Object Interrupt Flag bit
1 = Transmit object interrupt is pending
0 = No transmit object interrupts are pending
Note 1: C1INTL: Flags are set by hardware and cleared by application.
