AUTOCHSEL: Auto Channel Select bit
1 = Enabled – AFE selects channel(s) that has demodulator output “high” at the end of TSTAB; or otherwise, blocks the
channel(s).
0 = Disabled – AFE follows channel enable/disable bits defined in Register 0
AGCSIG: Demodulator Output Enable bit, after the AGC loop is active
1 = Enabled – No output until AGC is regulating at around 20 mVPP at input pins. The AGC Active Status bit is set
when the AGC begins regulating.
0 = Disabled – the AFE passes signal of any level it is capable of detecting
MODMIN<1:0>: Minimum Modulation Depth bit
00 = 50%
01 = 75%
10 = 25%
11 = 12%
LCZSEN<3:0>(1): LCZ Sensitivity Reduction bit
0000 = -0dB (Default)
:
1111 = -30dB
R5PAR: Register Parity bit – set/cleared so the 9-bit register contains odd parity – an odd number of set bits
Note 1: Assured monotonic increment (or decrement) by design.
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
