Legend:
R = Readable bit
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
-n = Value at POR
bit 8-7
bit 6-1
Unimplemented: Read as ‘0’
LCZTUN<5:0>: LCZ Tuning Capacitance bit
000000= +0 pF (Default)
:
111111= +63 pF
bit 0
R3PAR: Register Parity Bit – set/cleared so the 9-bit register contains odd parity – an odd number of set
