7.9
This section describes how several scenarios for the Enhanced ShockBurst™ automatic transaction han-
dling. The call outs in this section’s figures indicate the IRQs and other events. For MCU activity the event
may be placed at a different timeframe.

In
received by the PRX the ACK packet is transmitted from the PRX to the PTX. The RX_DR IRQ is asserted
after the packet is received by the PRX, whereas the TX_DS IRQ is asserted when the packet is acknowl-
edged and the ACK packet is received by the PTX.
