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 bits
bit 8
RSSIFET: Pull-down MOSFET on LFDATA pad bit (controllable by user in the RSSI mode only)
1 = Pull-down RSSI MOSFET on
0 = Pull-down RSSI MOSFET off
CLKDIV: Carrier Clock Divide-by bit
1 = Carrier Clock/4
0 = Carrier Clock/1
LCYTUN<5:0>: LCY Tuning Capacitance bit
000000 =+0 pF (Default)
111111 =+63 pF
R2PAR: Register Parity bit – set/cleared so the 9-bit register contains odd parity – an odd number of set bits
