0x1

0: straight line uniform function

1: straight line hill function (normal)

0x0

0: free-running

1: freeze scores

Set to a 1 when the microcontroller is

reading multibyte scores to prevent update

corruption.

width in pixels of the per frame scored area

= 2 ^ (3+ hblock_size)

FLK_FRAME_CNT_MAX

0x0CA3

R/W

[7:0]

0x8

number of frames to complete one

measurement

total number of pixels in a line is:

frame_cnt_max * (2 ^ (3+hblock_size))

example: hblock_size = 4; frame_cnt_max

= 8;

In each frame only one portion of the image

is being scored. The width of that portion is

2 ^ (3 + hblock_size) = 128 pixels and the

height is the full height of the image. Thus

the total scored area after 8 frames is

128*8 = 1024 pixels wide.
