X-axis and Y-axis resolution reporting mode via Rpt_Mod bit = 1 in Configuration_II register. The setting in this
register will be inactive if Rpt_Mod bit = 0. The approximate resolution value for each register setting can be cal-
culated using the following formula. Each bit change is~90cpi. The minimum write value is 0x01 and maximum
is 0x37.
Resolution value (counts per inch, cpi) = RES [7:0] x 90
size.
