DETAILS
FTOVAL<7:0>: Floor Threshold OOK Value bits
The bits indicate Floor threshold in OOK receive mode.
FTOVAL<7:0> = 00001100 ≥ 6 dB (default)
FTOVAL assumes 0.5 dB RSSI Step
FSIZE<1:0>: FIFO Size Selection bits
These bits set the size/number of FIFO locations.
11 = 64 bytes
10 = 48 bytes
01 = 32 bytes
00 = 16 bytes (default)
FTINT<5:0>: FIFO Threshold Interrupt bits
Setting these bits selects the FIFO threshold for interrupt source. Refer to Section 3.6.2 “Interrupt
Sources and Flags” for additional information.
FTINT<5:0> = 001111 (default)
FIFO_THRESHOLD interrupt source’s behavior depends on the running mode (TX, RX or Stand-by
mode).
