Page 0/Register 19: MIC1LP/LINE1LP to Left-ADC Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 MIC1LP/LINE1LP Single-Ended vs Fully Differential Control. If MIC1LP/LINE1LP is selected to both left-
and right-ADC channels, both connections must use the same configuration (single-ended or fully
differential mode).
0: MIC1LP/LINE1LP is configured in single-ended mode.
1: MIC1LP/LINE1LP and MIC1LM/LINE1LM are configured in fully differential mode.
D6–D3 R/W 1111 MIC1LP/LINE1LP Input Level Control for Left-ADC PGA Mix
Setting the input level control to one of the following gains automatically connects LINE1L to the left-ADC
PGA mix.
0000: Input level control gain = 0 dB
0001: Input level control gain = –1.5 dB
0010: Input level control gain = –3 dB
0011: Input level control gain = –4.5 dB
0100: Input level control gain = –6 dB
0101: Input level control gain = –7.5 dB
0110: Input level control gain = –9 dB
0111: Input level control gain = –10.5 dB
1000: Input level control gain = –12 dB
1001–1110: Reserved. Do not write these sequences to these register bits.
1111: LINE1L is not connected to the left-ADC PGA.
D2 R/W 0 Left-ADC Channel Power Control
0: Left-ADC channel is powered down.
1: Left-ADC channel is powered up.
D1–D0 R/W 00 Left-ADC PGA Soft-Stepping Control
00: Left-ADC PGA soft-stepping at once per sample period
01: Left-ADC PGA soft-stepping at once per two sample periods
10–11: Left-ADC PGA soft-stepping is disabled.
Page 0/Register 20: Reserved Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7–D0 R 0111 1000 Reserved. Do not write to this register.
Page 0/Register 21: MIC1RP/LINE1RP to Left-ADC Control Register
BIT READ/ RESET DESCRIPTION
WRITE VALUE
D7 R/W 0 MIC1RP/LINE1RP Single-Ended vs Fully Differential Control. If MIC1RP/LINE1RP is selected to both left-
and right-ADC channels, both connections must use the same configuration (single-ended or fully
differential mode).
0: MIC1RP/LINE1RP is configured in single-ended mode.
1: MIC1RP/LINE1RP and MIC1RM/LINE1RM are configured in fully differential mode.
D6–D3 R/W 1111 MIC1RP/LINE1RP Input Level Control for Left-ADC PGA Mix
Setting the input level control to one of the following gains automatically connects LINE1R to the left-ADC
PGA mix.
0000: Input level control gain = 0 dB
0001: Input level control gain = –1.5 dB
0010: Input level control gain = –3 dB
0011: Input level control gain = –4.5 dB
0100: Input level control gain = –6 dB
0101: Input level control gain = –7.5 dB
0110: Input level control gain = –9 dB
0111: Input level control gain = –10.5 dB
1000: Input level control gain = –12 dB
1001–1110: Reserved. Do not write these sequences to these register bits.
1111: LINE1R is not connected to the left-ADC PGA.
D2–D0 R 000 Reserved. Write only zeros to these bits.
