CONFIGURATION REGISTERS SUMMARY
CONFIGURATION REGISTER 0 (ADDRESS: 0000)
OEH<1:0>: Output Enable Filter High Time (
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 (T
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 5.14.3 “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 0 Parity bit – set/cleared so the 9-bit register contains odd parity – an odd number of
set bits
