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
x = Bit is unknown
bit 8
bit 7
bit 6-5
bit 4-1
bit 0
Recommended to write ‘0’: This bit has no effect in the MCP2035.
AGCSIG: Demodulator Output Enable bit, after the AGC loop is active
1 = Enabled – No output until AGC is regulating at around 20 mV_PP at input pin. The AGC Active Sta-
tus bit is set when the AGC begins regulating.
0 = Disabled – The device passes signal of any level it is capable of detecting
MODMIN<1:0>: Minimum Modulation Depth bit
00 = 33%
01 = 60%
10 = 14%
11 = 8%
Recommended to all 0’s. (Note 1)
R5PAR: Register 5 Parity bit – set or cleared (1 or 0) so the 9-bit register contains odd parity – an odd
number of set bits. An incorrect parity bit may draw unnecessary extra current.
Note 1: These bits are associated to the internally grounded LCZ sensitivity control.
