The packet is repeatedly retransmitted as
long as CE is high. TX_REUSE is set by the
SPI command REUSE_TX_PL, and is reset
by the SPI command W_TX_PAYLOAD
or FLUSH TX
TX FIFO full flag
1: TX FIFO full; 0: Available locations in
TX FIFO
TX FIFO empty flag.
1: TX FIFO empty
0: Data in TX FIFO
Only '00' allowed
RX FIFO full flag
1: RX FIFO full
0: Available locations in RX FIFO
RX FIFO empty flag
1: RX FIFO empty
0: Data in RX FIFO
Written by separate SPI command ACK
packet payload to data pipe number PPP
given in SPI command
Used in RX mode only
Maximum three ACK packet payloads can
be pending. Payloads with same PPP are
handled first in first out.
Written by separate SPI command TX data
pay-load register 1 - 32 bytes. This register
is implemented as a FIFO with three levels.
Used in TX mode only
Read by separate SPI command
RX data payload register. 1 - 32 bytes.
