Bit Name Reset Access Description
31:23 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
22 DEBUGRUN 0 RW Debug Mode Run Enable
Set to keep LESENSE running in debug mode.
Value Description
0 LESENSE can not start new scans in debug mode
1 LESENSE can start new scans in debug mode
21:20 DMAWU 0x0 RW DMA wakeup from EM2
Value Mode Description
0 DISABLE No DMA wakeup from EM2
1 BUFDATAV DMA wakeup from EM2 when data is valid in the result buffer
2 BUFLEVEL DMA wakeup from EM2 when the result buffer is full/halffull depending on BUFIDL
configuration
19 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
18 BUFIDL 0 RW Result buffer interrupt and DMA trigger level
Value Mode Description
0 HALFFULL DMA and interrupt flags set when result buffer is halffull
1 FULL DMA and interrupt flags set when result buffer is full
17 STRSCANRES 0 RW Enable storing of SCANRES
When set, SCANRES will be stored in the result buffer after each scan
16 BUFOW 0 RW Result buffer overwrite
If set, LESENSE will always write to the result buffer, even if it is full
15:14 Reserved
To ensure compatibility with future devices, always write bits to 0. More information in Section 2.1 (p. 3)
13 DUALSAMPLE 0 RW Enable dual sample mode
When set, both ACMPs will be sampled simultaneously.
