BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 Decay Time Register Selection
0: Decay time for the Left AGC is generated from Register 26.
1: Decay time for the Left AGC is generated from this Register.
D6-D5 R/W 00 Baseline AGC Decay time
00: Left AGC Decay time = 50-msec
01: Left AGC Decay time = 150-msec
10: Left AGC Decay time = 250-msec
11: Left AGC Decay time = 350-msec
D4-D2 R/W 000 Multiplication Factor for Baseline AGC
000: Multiplication factor for the baseline AGC Decay time = 1
001: Multiplication factor for the baseline AGC Decay time = 2
010: Multiplication factor for the baseline AGC Decay time = 4
011: Multiplication factor for the baseline AGC Decay time = 8
100: Multiplication factor for the baseline AGC Decay time = 16
101: Multiplication factor for the baseline AGC Decay time = 32
110: Multiplication factor for the baseline AGC Decay time = 64
111: Multiplication factor for the baseline AGC Decay time = 128
D1-D0 R/W 00 Reserved. Write only zero to these register bits.
(1) Decay time is limited based on NADC ratio that is selected. For
NADC = 1, Max Decay time = 4 seconds
NADC = 1.5, Max Decay time = 5.6 seconds
NADC = 2, Max Decay time = 8 seconds
NADC = 2.5, Max Decay time = 9.6 seconds
NADC = 3 or 3.5, Max Decay time = 11.2 seconds
NADC = 4 or 4.5, Max Decay time = 16 seconds
NADC = 5, Max Decay time = 19.2 seconds
NADC = 5.5 or 6, Max Decay time = 22.4 seconds
