CS53L21
Power Down PGA X (PDN_PGAX)
Default: 0
0 - Disable
1 - Enable
Function:
PGA channel x will either enter a power-down or muted state when this bit is enabled. See
Power Control
1 (Address 02h) Note 1
above.
This bit is used in conjunction with AINx_MUX bits to determine the analog input path to the ADC. Refer to
“ADCX Input Select Bits (AINX_MUX[1:0])” on page 47
for the required settings.
Power Down ADC X (PDN_ADCX)
Default: 0
0 - Disable
1 - Enable
Function:
ADC channel x will either enter a power-down or muted state when this bit is enabled. See Note
1 on page
40.
Power Down (PDN)
Default: 0
0 - Disable
1 - Enable
Function:
The entire A/D will enter a low-power state when this function is enabled. The contents of the control port
registers are retained in this mode.

Auto-Detect Speed Mode (AUTO)
Default: 1
0 - Disable
1 - Enable
Function:
Enables the auto-detect circuitry for detecting the speed mode of the A/D when operating as a slave. When
AUTO is enabled, the MCLK/LRCK ratio must be implemented according to
Table 3 on page
30. The
SPEED[1:0] bits are ignored when this bit is enabled. Speed is determined by the MCLK/LRCK ratio.
