Usage

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).

Description

Reset

Full chip reset

0 = Normal operation mode (Default)

1 = Full chip reset

MotSwk

MOTSWK pin output selection (see Section 7)

0 = Motion function output (Default)

1 = SWKINT function output

Note that MOTSWK is chip pin, MotSwk is Configuration register bit

Bit [5:4]

MUST always be 00

PD_enh

Power down mode

0 = Normal operation (Default)

1 = Power down mode
