Field

Data Type: Bit field.

USAGE: This register allows the user to change the Y-axis resolution when the sensor is configured to have indepedent

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
