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

OEH<1:0>: Output Enable Filter High Time (TOEH) bit
00 = Output Enable Filter disabled (no wake-up sequence required, passes all signal to LFDATA)
01 = 1 ms
10 = 2 ms
11 = 4 ms
OEL<1:0>: Output Enable Filter Low Time (TOEL) bit
00 = 1 ms
01 = 1 ms
10 = 2 ms
11 = 4 ms
ALRTIND: ALERT bit, output triggered by:
1 = Parity error and/or expired Alarm timer (receiving noise, see Section 11.14.3 “Alarm Timer”)
0 = Parity error
LCZEN: LCZ Enable bit
1 = Disabled
0 = Enabled
LCYEN: LCY Enable bit
1 = Disabled
0 = Enabled
LCXEN: LCX Enable bit
1 = Disabled
0 = Enabled
R0PAR: Register Parity bit – set/cleared so the 9-bit register contains odd parity – an odd number of set bits
