is set by the SPI command

REUSE_TX_PL

, and is reset by the SPI commands

W_TX_PAYLOAD

or FLUSH TX

TX_FULL

TX FIFO full flag. 1: TX FIFO full. 0: Available loca-

tions in TX FIFO.

TX_EMPTY

TX FIFO empty flag.

1: TX FIFO empty.

0: Data in TX FIFO.

Reserved

3:2

R/W Only '00' allowed

RX_FULL

RX FIFO full flag.

1: RX FIFO full.

0: Available locations in RX FIFO.

RX_EMPTY

RX FIFO empty flag.
