LED_CTRL
LED Control Register
Access: Read/Write
Data Type: Eight bit unsigned integer.
USAGE: This register is used to control the LED operating mode.
MOTION_CTRL
Motion Control Register
Access: Read/Write
Data Type: Eight bit unsigned integer.
USAGE: This register is used to set the feature of MOTION interrupt output. If MOT_S bit is clear, the MOTION pin is level-
29
sensitive. With active low (MOT_A bit is clear) level-sensitive configuration, the MOTION pin will be driven low
when there is motion detected indicating there is motion data in DELTA_X and DELTA_Y registers. The mouse
microcontroller can read MOTION_ST register, DELTA_X register, and then DELTA_Y register sequentially. After
all the motion data has been read, DELTA_X and DELTA_Y registers will be zero, the MOTION pin will be driven
high by the sensor.
If MOT_S is set, the MOTION pin is edge sensitive. If MOT_A is also set, it means active high or rising edge
triggered. Whenever there is motion detected by the sensor, a pulse (~380ns) will be sent out through this
pin. This pulse can be used to trigger or wake the controller up from its sleep mode to read motion data from
the sensor. The controller can then read MOTION_ST register, DELTA_X register, and then DELTA_Y register
sequentially. (Refer to Motion Function for more information).
