Data Measurement Block

DMEAS_DMM_MODE_CTRL

0x0917

R/W

[7]

0x0

Listen to odd frame only. Applies only if the

odd signal is present from YUV. The results in

the Vertical Position algorithm are updated

with only the odd frame if this bit is set.

R/W

[6]

0x0

PCD algorithm

0: pixel < threshold

1: pixel >= threshold

R/W

[5]

0x0

horizontal position algorithm

0: pixel > threshold

1: abs (pixel - previous pixel) > threshold

R/W

[4]

0x0

clear DMM result registers

R/W

[3]

0x0

0: Do not freeze the results in Free-running

mode. New result will be available on the next

and subsequent toggle of the polling bit.

1: Freeze the current results in Free-running

mode. The polling bit will still toggle and the

block continues to free run; however, results

will not update.

No meaning in one-shot mode.

R/W

[2]

0x0

DMM measurement polling bit. Toggles at the

end of each measurement in free-run mode.

Undefined in one-shot mode.

R/W

[1]

0x0

DMM algorithm measurement start.

In free-run mode it enables measurements. In

one-shot mode it triggers the start of a

measurement and is reset to zero when the

measurement is complete.

R/W

[0]

0x0

0: DMM Free-running mode.

1: DMM One-shot mode.

DMEAS_DMM_DE_REF_L

DMEAS_DMM_DE_REF_H

0x0919

0x0

DE Size tolerance threshold value

DMEAS_DMM_DE_RST

0x091B

[7:1]

Reserved

R/W

[0]

0x0

Reset the DMM flag in One-shot mode

DMEAS_DATA_PHM_EDGE0

0x091C

[7:0]

Result of PHM edge intensity algorithm

DMEAS_DATA_PHM_EDGE1

0x091D

[7:0]

DMEAS_DATA_PHM_PSUM3

0x0923

[7:0]

DMEAS_DATA_DMM_MIN

0x0924

[7:0]

Result for DMM Minimum pixel value found.

DMEAS_DATA_DMM_MAX

0x0925

[7:0]

Result for DMM Maxmum pixel value found.
