MEAS_SEQR_APERS_AND_VSYNC_WAIT

Bit

Field

Reset

Type

Bit Description

7:4

MEASUREMENT_

SEQUENCER_VSYNC_

WAIT_PATTERN

0R/W

Defines if a measurement sequence shall wait for a

vsync before starting the measurement. The bit

pattern does not represent a value but controls

bitwise which sequencer step shall be used. The

leftmost position of “0000” refers to sequencer step

3, the rightmost refers to sequencer step 0.

3:0

MEASUREMENT_

SEQUENCER_APERS_

PATTERN

0x1

R/W

Defines the sequencer steps where an ALS

persistence evaluation shall be performed on

modulator data selected by ALS_THRESHOLD_

CHANNEL. The bit pattern does not represent a value

but controls bitwise which sequencer step shall be

used. The leftmost position of “0000” refers to

sequencer step 3, the rightmost refers to sequencer

step 0. By default step 0 is used on all modulators.

Addr: 0xD2

MEAS_SEQR_RESIDUAL_0

Bit

Field

Reset

Type

Bit Description

7:4

MEASUREMENT_

SEQUENCER_MOD1_

RESIDUAL_ENABLE_

PATTERN

0xF

R/W

Defines if a residual measurement on modulator 1 shall

be executed. The bit pattern does not represent a value

but controls bitwise which sequencer step shall be used.

The leftmost position of “0000” refers to sequencer step

3, the rightmost refers to sequencer step 0. By default a

residual measurement is done in all sequencer steps

be executed. The bit pattern does not represent a value

but controls bitwise which sequencer step shall be used.

The leftmost position of “0000” refers to sequencer step

3, the rightmost refers to sequencer step 0. By default a
