Description

Configuration Register

Fields

SCANMODE

Configure scan mode

0 (PERIODIC): A new scan is started each time the period counter overflows

1 (ONESHOT): A single scan is performed when START in CMD is set

2 (PRS): Pulse on PRS channel

SCANCONF

Select scan configuration

0 (DIRMAP): The channel configuration register registers used are directly mapped to the channel number.

1 (INVMAP): The channel configuration register registers used are CHX+8_CONF for channels 0-7 and CHX-8_CONF for channels 8-15.

2 (TOGGLE): The channel configuration register registers used toggles between CHX_CONF and CHX+8_CONF when channel x triggers

3 (DECDEF): The decoder state defines the CONF registers to be used.

DUALSAMPLE

Enable dual sample mode

STRSCANRES

Enable storing of SCANRES

DMAWU

DMA wake-up from EM2

0 (DISABLE): No DMA wake-up from EM2

1 (ENABLE): DMA wake-up from EM2 when FIFO count is greater or equal to RESFIDL

RESFIDL

Result FIFO level

DEBUGRUN

Debug Mode Run Enable

0 (X0): LESENSE can not start new scans in debug mode

1 (X1): LESENSE can start new scans in debug mode
