21 TXE TX FIFO is Empty
0 = TX FIFO is not empty.
1 = TX FIFO is empty and underflow will take
place if no more data is written.
RO 0x1
20 RXD Indicates that the RX FIFO contains data
0 = RX FIFO is empty.
1 = RX FIFO contains at least 1 sample.
RO 0x0
19 TXD Indicates that the TX FIFO can accept data
0 = TX FIFO is full and so cannot accept more
data.
1 = TX FIFO has space for at least 1 sample.
RO 0x1
18 RXR Indicates that the RX FIFO needs reading
0 = RX FIFO is less than RXTHR full.
1 = RX FIFO is RXTHR or more full.
This is cleared by reading sufficient data from
the RX FIFO.
RO 0x0
17 TXW Indicates that the TX FIFO needs Writing
0 = TX FIFO is at least TXTHR full.
1 = TX FIFO is less then TXTHR full.
This is cleared by writing sufficient data to the
TX FIFO.
RO 0x1
16 RXERR RX FIFO Error
0 = FIFO has had no errors.
1 = FIFO has had an under or overflow error.
This flag is cleared by writing a 1.
RW 0x0
15 TXERR TX FIFO Error
0 = FIFO has had no errors.
1 = FIFO has had an under or overflow error.
This flag is cleared by writing a 1.
RW 0x0
14 RXSYNC RX FIFO Sync
0 = FIFO is out of sync. The amount of data left
in the FIFO is not a multiple of that required for a
frame. This takes into account if we are halfway
through the frame.
1 = FIFO is in sync.
RO 0x0
13 TXSYNC TX FIFO Sync
0 = FIFO is out of sync. The amount of data left
in the FIFO is not a multiple of that required for a
frame. This takes into account if we are halfway
through the frame.
1 = FIFO is in sync.
RO 0x0
