Figure 60. Occurrence of the TX FIFO Almost Empty Interrupt
10.18. Long Packet Reception
Applications requiring packet length greater than the RX FIFO sizes (64 bytes) may use the long packet feature of
the radio. In such a case, RX FIFO Almost Full interrupts should be monitored for proper timing to read the RX
FIFO. To determine when the Almost Full interrupt should actually occur, a threshold level can be set. As for the RX
side of the link, the RX FIFO Almost Full and Packet Sent interrupts have to be enabled during initialization. After
sending a START_RX command, the host MCU begins waiting for the RX FIFO Almost Full IT. When it arrives, it
reads out RX_THRESHOLD number of bytes from the RX FIFO and continues waiting for the next RX FIFO Almost
Full interrupt, etc. If the expected bytes are less than RX_THRESHOLD, the host MCU should wait for the packet
received interrupt.
