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 31

Unimplemented: Read as ‘0’

bit 30-24

RXCODE<6:0>: Receive Interrupt Flag Code bits( 1)

1000001-1111111 = Reserved

1000000 = No interrupt

0100000-0111111 = Reserved

0011111 = FIFO 31 Interrupt (RFIF<31> set)

...

0000010 = FIFO 2 Interrupt (RFIF<2> set)

0000001 = FIFO 1 Interrupt (RFIF<1> set)

0000000 = Reserved. FIFO 0 can’t receive.

bit 23

Unimplemented: Read as ‘0’

bit 22-16

TXCODE<6:0>: Transmit Interrupt Flag Code bits( 1)

1000001-1111111 = Reserved

1000000 = No interrupt

0100000-0111111 = Reserved

0011111 = FIFO 31 Interrupt (TFIF<31> set)

...

0000001 = FIFO 1 Interrupt (TFIF<1> set)

0000000 = TXQ Interrupt (TFIF<0> set)

bit 15-13

Unimplemented: Read as ‘0’

bit 12-8

FILHIT<4:0>: Filter Hit Number bits( 1)

11111 = Filter 31

11110 = Filter 30

...

00001 = Filter 1

00000 = Filter 0

Note 1:

If multiple interrupts are pending, the interrupt with the highest number will be indicated.
