WIRELESS & SENSING
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.
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=11). 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.
