„ Write packet bytes into FIFO. Tx starts when the first byte is written (Tx_start_irq_0=1). We assume the FIFO is
being filled via SPI Data faster than being unfilled by SR (else use Tx_start_irq_0=0 ie Fifo_threshold to delay
Tx start)
„ Wait for Tx_done interrupt (+1 bit period)
„ Go to Sleep mode
Rx Mode:
„ Program Rx/Stby interrupts: IRQ_0 mapped to /Fifoempty (Rx_stby_irq_0=10) and IRQ_1 mapped to
Fifo_threshold (Rx_stby_irq_1=01). Configure Fifo_thresh to an appropriate value (ex: to detect packet end if
its length is known)
„ Go to Rx mode (note that Rx is not ready immediately, Cf section 7.3.1).
„ Wait for Fifo_threshold interrupt (i.e. Sync word has been detected and FIFO filled up to the defined threshold).
„ If it is packet end, go to Stby (SR’s content is lost).
„ Read packet bytes from FIFO until /Fifoempty goes low (or correct number of bytes is read).
„ Go to Sleep mode.
