- Automatically starts when a sync word is detected (d)

- Manually controlled by Fifo_fill

Fifo_fill

r/w/

FIFO filling status/control (Buffered mode only):

•

If Fifo_fill_method =

„0‟: (d)

Goes high when FIFO is being filled (sync word has been detected)

Writing

„1‟ clears the bit and waits for a new sync word (if Fifo_overrun_clr=0)

•

If Fifo_fill_method =

„1‟:

- Stop filling the FIFO

- Start filling the FIFO

Tx_done

Tx_done IRQ source

Goes high when the last bit has left the shift register.

Tx_start_irq_0

r/w

Tx start condition and IRQ_0 source:

•

If Data_mode(1:0) = 01 (Buffered mode):

- Tx starts if FIFO is full, IRQ_0 mapped to /Fifoempty (d)

- Tx starts if FIFO is not empty, IRQ_0 mapped to /Fifoempty

•

If Data_mode(1:0) = 1x (Packet mode):

- Start transmission when the number of bytes in FIFO is greater than or

equal to the threshold set by MCParam_Fifo_thresh parameter (Cf section

5.2.2.3), IRQ_0 mapped to Fifo_threshold (d)

- Tx starts if FIFO is not empty, IRQ_0 mapped to /Fifoempty

Res

r/w

(d):

“0”, should be set to “1”.

Note:

“0” disables the RSSI IRQ source. It can be left enabled at any time, and

the user can choose to map this interrupt to IRQ0/IRQ1 or not.

RSSI_irq

r/w/

RSSI IRQ source:

Goes high when a signal above RSSI_irq_thresh is detected

Writing

„1‟ clears the bit

PLL_locked

r/w/

PLL status:

- not locked

- locked

Writing a

„1‟ clears the bit

PLL_lock_en

r/w

PLL_lock detect flag mapped to pin 23:

- Lock detect disabled, pin 23 is High-Z

- Lock detect enabled(d)

RSSI_irq_thresh

7-0

RSSI threshold for interrupt (coded as RSSI)

(d):

“00000000”
