Fields

SARADC_START_FORCE
SARADC_START
SARADC_SAR2_MUX

1: SAR ADC2 is controlled by DIG ADC2 CTRL 0: SAR ADC2 is controlled by PWDET CTRL
SARADC_WORK_MODE

0: single mode 1: double mode 2: alternate mode
SARADC_SAR_SEL

0: SAR1 1: SAR2 only work for single SAR mode
SARADC_SAR_CLK_GATED
SARADC_SAR_CLK_DIV

SAR clock divider
SARADC_SAR1_PATT_LEN

0 ~ 15 means length 1 ~ 16
SARADC_SAR2_PATT_LEN

0 ~ 15 means length 1 ~ 16
SARADC_SAR1_PATT_P_CLEAR

clear the pointer of pattern table for DIG ADC1 CTRL
SARADC_SAR2_PATT_P_CLEAR

clear the pointer of pattern table for DIG ADC2 CTRL
SARADC_DATA_SAR_SEL

1: sar_sel will be coded by the MSB of the 16-bit output data in this case the resolution should not be larger than 11 bits.
SARADC_DATA_TO_I2S

1: I2S input data is from SAR ADC (for DMA) 0: I2S input data is from GPIO matrix
