Reset Access Description
0 RW Selects ASYNC CLK Enable Mode When ADCCLKMODE=1
Mode Description
ASNEEDED ASYNC CLK is enabled only during ADC Conversion.
ALWAYSON ASYNC CLK is always enabled.
To ensure compatibility with future devices, always write bits to 0. More information in
tions
0 RW Conversion Tailgating
Description
Scan sequence has priority, but can be delayed by ongoing single
channels.
Scan sequence has priority and single channels will only start immedi-
ately after completion of a scan sequence.
0 RW SCANFIFO DMA Wakeup
Description
While in EM2, the DMA controller will not get requests about DVL
reached in SCANFIFO
DMA is available in EM2 for processing SCANFIFO DVL request
0 RW SINGLEFIFO DMA Wakeup
Description
While in EM2, the DMA controller will not get requests about Data Valid
Level (DVL) reached in SINGLEFIFO
DMA is available in EM2 for processing SINGLEFIFO DVL request
0x0 RW Warm-up Mode
Mode Description
NORMAL ADC is shut down after each conversion. 5us warmup time is used be-
fore each conversion.
KEEPINSTANDBY ADC is kept in standby mode between conversions. 1us warmup time
is used before each conversion.
KEEPINSLOWACC ADC is kept in slow acquisition mode between conversions. 1us warm-
up time is used before each conversion.
KEEPADCWARM ADC is kept on after conversions, allowing for continuous conversion.
