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 8-7
bit 6-1
bit 0
DATOUT<1:0>: LFDATA Output type bit
00 = Demodulated output
01 = Carrier Clock output
10 = RSSI output
11 = RSSI output
LCXTUN<5:0>: LCX Tuning Capacitance bit
000000 = +0 pF (Default)
:
111111 = +63 pF
R1PAR: Register Parity Bit – set/cleared so the 9-bit register contains odd parity – an odd number of set
