Description
Reserved, read as 0.
TX active indicates transmission in progress
0 : TX inactive
1 : TX active
RXFIFO data available
0 : No data available in RXFIFO
1 : One or more bytes available in RXFIFO
RXFIFO threshold flag
0 : Number of bytes in RXFIFO is less or equal threshold
set by IOCFG0.FIFOP_THR
1 : Number of bytes in RXFIFO is greater than threshold set
by IOCFG0.FIFOP_THR
Note that if frame filtering/address recognition is enabled
this bit is set only when the frame has passed filtering. This
bit is also set when a complete frame has been received.
