This bit must be cleared to 0 for normal operation. When set to 1, it forces a block-wide reset.
This bit must be cleared to 0 for normal operation. When set to 1, it gates off the clocks to the block.
This bit field specifies the trigger mode of ADC.Take effect when hsadc_run is asserted.
00: ADC is triggered by the software.
01: ADC is triggered by the PWM trigger signal.
10: ADC is triggered by the input signal from outside the chip.
