DMEAS_MODE_CTRL

0901

R/W

[7]

DE reset

0*: do not reset the de_mismatch_flag

1: reset the de_mismatch_flag

R/W

[6]

DE freeze

0*: update I2C registers after every measurement in free

run mode

1: freeze DE size results in I2C registers and do not

update while this bit is active

R/W

[5]

DE one shot

0*: free run mode.

1: one shot mode.

Applies only to DE_Size measurement. All other

measurements are always in One_shot mode.

R/W

[3]

h_v_pos_sel / pcd_sel

- if algorithm = 01 (pcd_sel)

0*: pixel < threshold

1: pixel >= threshold

- if algorithm = 10 (h_v_pos_sel)

0*: pixel > threshold (normal)

1: abs (pixel - previous pixel) > threshold

R/W

[2]

DMEAS all clear

All internal result registers are cleared when this bit is

set. This bit is self clearing.

[1]

DMEAS polling bit.

Toggles at the end of each measurement in free-run

mode. Undefined in one-shot mode.

R/W

[0]

DMEAS start

Data measurement start. This bit is auto-cleared by HW

when the measurement is completed.

0902

R/W

[7:0]

Threshold value to use for selected algorithm.
