The Configuration register allows the user to change the configuration of the sensor. Shown below are
the bits, their default values, and optional values.
If MotSwk bit is clear, the MOTSWK pin is level-sensitive. The pin level remains low when motion
has occurred; in other words, Delta_X and Delta_Y registers has data. The mouse controller can read
Motion_Status register, Delta_X register, then Delta_Y register sequentially. After the mouse
controller reads all data, Delta_X and Delta_Y are both zero, the pin level will be high (see Section 7).
If MotSwk bit is set, the MOTSWK pin is edge-sensitive. The pin will send a pulse and trigger the
mouse controller when motion has occurred during the sleep mode. The mouse controller can read
Motion_Status register, Delta_X register, then Delta_Y register sequentially (see Section 7).
