(1)
R-0 R-0 R-0 R-0 R-0 R-0 R-0 R-0
TFATIF<31:24>
bit 15 bit 8
R-0 R-0 R-0 R-0 R-0 R-0 R-0 R-0
TFATIF<23:16>
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 TFATIF<31:16>: Transmit FIFO/TXQ Attempt Interrupt Pending bits
1 = Interrupt is pending
0 = Interrupt is not pending
Note 1: C1TXATIFH: FIFO: TFATIFx (flag needs to be cleared in the FIFO register).
