The value of the HPF corner frequency also depends on the input sample rate (SR1) as shown in Table 31 (ADC
in high power mode) and Table 32 (ADC in low power mode). Note that when operating in ADC low power mode
(adc_lp_mode = 1), the voice filter is only available at a sample rate of 8 kHz. Similarly the audio filter will not
operate at sample rates of 32 kHz, 88.2 kHz, or 96 kHz.
The sample rates available in the different ADC power modes are summarized in Table 31 for the ADC in high-
power mode (adc_lp_mode = 0), and Table 32 for the ADC in low-power mode (adc_lp_mode = 1).
