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 7-5
bit 4-2
bit 1-0
OOKTHSV<2:0>: OOK Threshold Step Value bits
These bits set the size of each decrement of the RSSI threshold in the OOK demodulator.
111 = 6.0 dB
110 = 5.0 dB
101 = 4.0 dB
100 = 3.0 dB
011 = 2.0 dB
010 = 1.5 dB
001 = 1.0 dB
000 = 0.5 dB (default)
OOKTHPV<2:0>: OOK Threshold Period Value bits
These bits set the period of decrement of the RSSI threshold in the OOK demodulator.
111 = 16 times in each chip period
110 = 8 times in each chip period
101 = 4 times in each chip period
100 = twice in each chip period
011 = once in each 8 chip periods
010 = once in each 4 chip periods
001 = once in each 2 chip periods
000 = once in each chip period (default)
OOKATHC<1:0>: OOK Average Threshold Cut-off bits
These bits set the cut-off frequency of the averaging for the average mode of the OOK threshold in the
demodulator.
11 = f c ~ BR/32. π (1)
10 = Reserved; do not use
01 = Reserved; do not use
00 = f c ~ BR/8. π (default) (1)
Note 1: BR is the bit rate (for more information, refer to BRSREG ( Register 2-22 )).
