Legend:
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 7
RX1OVR: Receive Buffer 1 Overflow Flag bit
- Set when a valid message is received for RXB1 and CANINTF.RX1IF = 1
- Must be reset by MCU
bit 6
RX0OVR: Receive Buffer 0 Overflow Flag bit
- Set when a valid message is received for RXB0 and CANINTF.RX0IF = 1
- Must be reset by MCU
bit 5
TXBO: Bus-Off Error Flag bit
- Bit set when TEC reaches 255
- Reset after a successful bus recovery sequence
bit 4
TXEP: Transmit Error-Passive Flag bit
- Set when TEC is equal to or greater than 128
- Reset when TEC is less than 128
bit 3
RXEP: Receive Error-Passive Flag bit
- Set when REC is equal to or greater than 128
- Reset when REC is less than 128
bit 2
TXWAR: Transmit Error Warning Flag bit
- Set when TEC is equal to or greater than 96
- Reset when TEC is less than 96
bit 1
RXWAR: Receive Error Warning Flag bit
- Set when REC is equal to or greater than 96
- Reset when REC is less than 96
bit 0
EWARN: Error Warning Flag bit
- Set when TEC or REC is equal to or greater than 96 (TXWAR or RXWAR = 1)
-
Reset when both REC and TEC are less than 96
