10 VS1005 PERIPHERALS AND REGISTERS  
AD_CF_AD23_FLP register flips the input of filters 2 and 3.  
FM decimation filter is used when FM is enabled and it decimates the FM signals to 32kHz. The  
filter can be used in cascade with other filters. Register AD_CF_DEC6SEL is used to select  
filter input.

AD_CF_AD3FS and AD_CF_ADFS registers select the AD filters’s decimation factor (sample  
rate). Exact sample rate is xtal dependent.
