Recommended value 0x2 when HSADC works at 1.5 MHz sampling rate with DCDC working. This
configuration can attenuate the impact of DCDC noise on HSADC performance only when HSADC working
at 1.5 MHz sampling rate, and the configuration is available only when set SLOW_DITHER to 0x1.
Reserved
INDIV<2>: Set 1 for HSADC working at 1.5 MHz sampling rate. INDIV<1:0>: Recommended value 0x2 when
HSADC works at 1.5 MHz sampling rate with DCDC working. This configuration can attenuate the impact
of DCDC noise on HSADC performance only when HSADC working at 1.5 MHz sampling rate, and the
configuration is available when set SLOW_DITHER to 0x1 or using PWM trigger for HSADC.
