ADP_BUF_SEL
– Select data to be routed to the sample buffer
ADP_BUF_SEL = 0
– Accelerometer data is routed to the sample buffer (default)
ADP_BUF_SEL = 1
– ADP data is routed to the sample buffer. Note, if ADP data sent to the
sample buffer bypasses the RMS block (ADP_RMS_OSEL = 0), the data is buffered at
ODR set by the OADP<3:0>. If not, the effective ODR is scaled down by RMS_AVC<2:0>
setting.
ADP_WB_ISEL
– Input select for the Wake-up/Back-to-Sleep engines
ADP_WB_ISEL = 0
– Accelerometer data is selected (ADP data is bypassed)
ADP_WB_ISEL = 1
– ADP data is selected. Note, ODR for the Wake-up / Back-to-Sleep would
be set but OADP<3:0> and not by OWUF<2:0> and OBTS<2:0>.
RMS_WB_OSEL
– RMS select data for the Wake-up/Back-to-Sleep engines. Note: ADP_WB_ISEL
bit should be set to 1 for this control to have an effect.
RMS_WB_OSEL = 0
– Output data from ADP is not routed to the Wake-up/Back-to-Sleep
engines
RMS_WB_OSEL = 1
– ADP RMS output data is routed to the Wake-up/Back-to-Sleep
engines.
ADP_FLT2_BYP
– Advanced Data Path Filter-2 bypass control
ADP_FLT2_BYP = 0
– Filter-2 is not bypassed
ADP_FLT2_BYP = 1
– Filter-2 is bypassed
ADP_FLT1_BYP
– Advanced Data Path Filter-1 bypass control
ADP_FLT1_BYP = 0
– Filter-1 is not bypassed
ADP_FLT1_BYP = 1
– Filter-1 is bypassed
ADP_RMS_OSEL
– Select data out to XADP, YADP, ZADP registers and to the output buffer. Note,
ADP_RMS_OSEL must be set to 1 if RMS_WB_OSEL is set to 1.
ADP_RMS_OSEL = 0
– Filter output (RMS engine is bypassed)
ADP_RMS_OSEL = 1
– RMS output
ADP_F2_HP
– Filter-2 High-pass enable
ADP_F2_HP = 0
– Filter-2 is set to Low-pass filter
ADP_F2_HP = 1
– Filter-2 is set to High-pass filter
