2 (PRS): Pulse on PRS channel

PRSSEL

Scan Start PRS Select

0 (PRSCH0): PRS Channel 0 selected as input

1 (PRSCH1): PRS Channel 1 selected as input

2 (PRSCH2): PRS Channel 2 selected as input

3 (PRSCH3): PRS Channel 3 selected as input

14 (PRSCH14): PRS Channel 14 selected as input

15 (PRSCH15): PRS Channel 15 selected as input

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.

ALTEXMAP

Alternative Excitation Map

DUALSAMPLE

Enable Dual Sample Mode

BUFOW

Result Buffer Overwrite

STRSCANRES

Enable Storing of SCANRES

BUFIDL

Result Buffer Interrupt and DMA Trigger Level

DMAWU

DMA Wake-up From EM2

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

1 (BUFDATAV): DMA wake-up from EM2 when data is valid in the result buffer

2 (BUFLEVEL): DMA wake-up from EM2 when the result buffer is full/half-full depending on BUFIDL configuration

DEBUGRUN

Debug Mode Run Enable
