User manual Transceiver module TXRX01 • RX three level, 32 byte FIFO Both FIFOs have a controller and are accessible through the SPI by using dedicated SPI commands. A TX FIFO in PRX can store payloads for ACK packets to three different PTX devices. If the TX FIFO contains more than one payload to a pipe, payloads are handled using the first in - first out principle. - Page 11 User manual Transceiver module TXRX01 Address Mnemonic Reset Type Description (Hex) Value ENAA_P1 Enable auto acknowledgement data pipe 1 ENAA_P0 Enable auto acknowledgement data pipe 0 EN_RXADDR Enabled RX Addresses Reserved Only '00' allowed ERX_P5 Enable data pipe 5.
