DE reset
0*: do not reset the de_mismatch_flag
1: reset the de_mismatch_flag
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
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.
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
DMEAS all clear
All internal result registers are cleared when this bit is
set. This bit is self clearing.
DMEAS polling bit.
Toggles at the end of each measurement in free-run
mode. Undefined in one-shot mode.
DMEAS start
Data measurement start. This bit is auto-cleared by HW
when the measurement is completed.
