8.5 Error Detection

1. The mouse controller can verify success of write operations by issuing a read command to

the same address and comparing written data to read data.

8.6 MOTSWK function

8.6.1 Motion function

To use Motion function, the MOTSWK bit in the Configuration register must be set to zero.

Motion is used to monitor if the mouse sensor has finished sending X-Y movement data to the

mouse controller. If all movement data are not read, MOTSWK pin level will remain low. After the

mouse controller reads all movement data from the mouse sensor, the mouse sensor will set

MOTSWK pin level to high
