Enums

Acqmod

DFLT trigger mode. This bitfield is set and cleared by software. It is used to select the trigger mode of the DFLT0.

Bssel

Bitstream selection. This bitfield is set and cleared by software. It is used to select the bitstream to be used by the DFLT0.

Cckdir

CCK1 direction. This bit is set and reset by software. It is used to control the direction of the ADF_CCK1 pin.

Cckdiv

Divider to control the CCK clock. This bit is set and reset by software. It is used to control the frequency of the bitstream clock on the CCK pin.

Ccken

CCK clock enable. This bit is set and reset by software. It is used to control the generation of the bitstream clock on the CCK pin.

Cicmod

Select the CIC order. This bitfield is set and cleared by software. It is used to select the MCIC order.

Ckgmod

Clock generator mode. This bit is set and reset by software. It is used to define the way the clock generator is enabled. This bit must not be changed if the filter is enabled (DFTEN = 1).

Datcap

Data capture mode. This bitfield is set and cleared by software. It is used to define in which conditions, the samples provided by DLFT0 are stored into the memory.

Datsrc

Source data for the digital filter.

Detcfg

Sound trigger event configuration. This bit is set and cleared by software. It is used to define if the sddet_evt event is generated only when the SAD enters to MONITOR state or when the SAD enters or exits the DETECT state.

Frsize

Frame size. This bitfield is set and cleared by software. it is used to define the size of one frame and also to define how many samples are taken into account to compute the short-term signal level.

Hgovr

Hangover time window. This bitfield is set and cleared by software. It is used to select the hangover time window.

Hpfc

High-pass filter cut-off frequency. This bitfield is set and cleared by software. it is used to select the cut-off frequency of the high-pass filter. F PCM represents the sampling frequency at HPF input.

Lfrnb

LFRNB. This bitfield is set and cleared by software. It is used to define the number of learning frames to perform the first estimate of the noise level.

Rsfltd

Reshaper filter decimation ratio. This bitfield is set and cleared by software. It is used to select the decimation ratio of the reshaper filter.

Rxfifo

RXFIFO threshold selection. This bitfield is set and cleared by software. It is used to select the RXFIFO threshold.

Sadmod

SAD working mode. This bitfield is set and cleared by software. It is used to define the way the SAD works

Sadst

SAD state. This bitfield is set and cleared by hardware. It indicates the SAD state and is meaningful only when SADEN = 1.

Scksrc

Serial clock source. This bitfield is set and cleared by software. It is used to select the clock source of the serial interface.

Sitfmod

Serial interface mode. This bitfield is set and cleared by software. It is used to select the serial interface mode.

Snthr

SNTHR. This bitfield is set and cleared by software. It is used to select the gain to be applied at CIC output. If the application attempts to write a new gain value while the previous one is not yet applied, this new gain value is ignored. Reading back this bitfield informs the application on the current gain value.

Trgsens

CKGEN trigger sensitivity selection. This bit is set and cleared by software. It is used to select the trigger sensitivity of the trigger signals. This bit is not significant if the CKGMOD = 0.

Trgsrc

Digital filter trigger signal selection.
