Set 0x1 to make the configuration INDIV<1:0> and INCLK_SHIFT available, but there would be <= 0.67us
timing delay between HSADC start conversion and ‘start run’ command from software trigger or PWM trigger.
If this delay is not desired, it is recommended to set INDIV<1:0> to 0x2 and using PWM trigger for HSADC.
