bit 7
bit 0
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
r = Reserved
bit 7
bit 6
FIFOFM: FIFO Filling Method bits
This bit decides the method of filling FIFO (supports Buffer mode only)
1 = Manually controlled by FIFO fill
0 = Automatically starts when a sync word is detected (default)
FIFOFSC: FIFO Filling Status or Control bits
This bit indicate the status of FIFO filling and also controls the filling up of FIFO
(supports Buffer Mode only)
STATUS: Reading (FIFOFM = 0 )
1 = FIFO getting filled (
sync word has been detected)
0 = FIFO filling completed / stopped
CONTROL: Writing (FIFOFM = 1 ), clears the bit and waits for a new sync word (FOVRCLR = 0 )
1 = Start filling the FIFO
0 = Stop filling the FIFO
bit 5
bit 4
TXDONE: Transmit Done bit
This bit selects and IRQ source.
1 = TXDONE (goes high when the last bit has left the shift register).
0 = TX still in process
IRQ0TXST: Transmit Start with IRQ0 bit
This bit indicates transmit start condition with IRQ0 as source.
If DMODE1:DMODE0 = 01
Buffer Mode:
1 = Transmit starts if FIFO is not empty, IRQ0 mapped to FIFOEMPTY
0 = Transmit starts if FIFO is full, IRQ0 mapped to FIFOEMPTY (default)
If DMODE1:DMODE0 = 1x
Packet Mode:
1 = Transmit starts if FIFO is not empty, IRQ0 mapped to FIFOEMPTY
0 = Start transmission when the number of bytes in FIFO is greater than or equal to threshold set by
the FTINT<5:0> bits (FIFOCREG<5:0), IRQ0 mapped to FIFO_THRESHOLD
bit 3
bit 2
Reserved: Reserved bit
1 = Set bit to ‘ 1 ’ (required) (1)
0 = Reserved (default)
RIRQS: RSSI IRQ Source
This bit indicates IRQ source as RSSI
1 = Detected signal is above the value determined by the RTIVAL<7:0> bits (RSTHIREG<7:0>)
0 = Detected signal is less than the value determined by the RTIVAL<7:0> bits (RSTHIREG<7:0>)
Writing a ‘ 1 ’ for this bit clears RIRQS.
Note 1: Setting this bit to ‘ 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.
