RFIF<31:24>
bit 15 bit 8
R-0 R-0 R-0 R-0 R-0 R-0 R-0 R-0

bit 7 bit 0
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 15-0 RFIF<31:16>: Receive FIFO Interrupt Pending bits
1 = One or more enabled receive FIFO interrupts are pending
0 = No enabled receive FIFO interrupts are pending
Note 1: C1RXIFH: FIFO: RFIFx = ‘or’ of enabled RX FIFO flags (flags need to be cleared in the FIFO register).
