RATIO_ENG_DATA_n (production silicon)

Ratio engine -1, -2 data register

Address:

0x84-0x86, 0x87-0x89

Type:

Reset:

0x0000

Description:

Position of the touch as calculation output of Ratio Engine 1 and 2 Data is organized

as a "packet" of 3 bytes. The data is backed by 4-level of buffer

1st byte [7:0]

2nd byte [15:8]

3rd byte [23:16]

[7:0] POS:

Position of the touch in ratio engine sensors.

[15:8] MOV:

Movement of the touch location as a function of POS1 – POS0, where POS1 is current position

and POS0 is position before.

[23:16] TIME_STAMP:

Delay between current and previous samples in unit of time.

Each bit is 8ms (if MAF is enabled), or 1/4ms (if MAF is not enabled).
