Description
set bits to 00'b
Auto IDLE value when override bit is set (reg
0x08 [4] = 1)
Force IDLE value when override bit is set (reg
0x08 [4] = 1)
Set bit to 0'b
Set bits to 000'b
EQ Boost Default to 24 dB
See Table 2 for Information
1 = Short Circuit Protection ON
0 = Short Circuit Protection OFF
Set bit to 1'b
Set bits to = 101'b
Set bits to = 101'b
Set bits to = 100'b
Set bit to 0
Set bit to 0
De-Emphasis (Default = -3.5 dB)
000'b = -0.0 dB
