Description

DIG ADC common configuration

Fields

START_FORCE

0: select FSM to start SAR ADC. 1: select software to start SAR ADC.
START

Start SAR ADC by software.
WORK_MODE

0: single-channel scan mode. 1: double-channel scan mode. 2: alternate-channel scan mode.
SAR_SEL

0: select SAR ADC1. 1: select SAR ADC2, only work for single-channel scan mode.
SAR_CLK_GATED

SAR clock gate enable bit.
SAR_CLK_DIV

SAR clock divider
SAR1_PATT_LEN

0 ~ 15 means length 1 ~ 16
SAR2_PATT_LEN

0 ~ 15 means length 1 ~ 16
SAR1_PATT_P_CLEAR

Clear the pointer of pattern table for DIG ADC1 CTRL.
SAR2_PATT_P_CLEAR

Clear the pointer of pattern table for DIG ADC2 CTRL.
DATA_SAR_SEL

1: sar_sel will be coded to the MSB of the 16-bit output data, in this case the resolution should not be larger than 11 bits.
DATA_TO_I2S

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

Force option to xpd sar blocks.
WAIT_ARB_CYCLE

Wait arbit signal stable after sar_done.
