ATMDAD
ADC Attenuation mode
This bit controls the ADC attenuation mode. ATAD1[7:0] to ATAD6[7:0] are simply used for
ATMDAD = 0, and ATAD0[7:0] + ATAD1[7:0] to ATAD0[7:0] + ATAD6[7:0] in decibel number are
used for ATMDAD = 1.
Default value: 0.
ATMDAD
ADC Attenuation mode
0
Each channel with independent data (default)
All channels with preset (independent) data + master (common) data in decibel

number
ATSPAD
ADC Attenuation speed
This bit controls the ADC attenuation Speed, N × 2048/fS for ATSPAD = 0 and N × 4096/fS for
ATSPAD = 1. N is automatically selected according to the ADC sampling mode, SRAD: N = 1 for
single and N = 2 for dual rate.
Default value: 0.

OVFP
ADC Overflow flag polarity select
This bit controls the polarity of the overflow flag pin.
Default value: 0.
