FUNCTION DESCRIPTIONS
1.SERIAL SCROLLING MOUSE
In Microsoft mode, the transmission cycle consists of four bytes in one report. Each byte contains one start bit, 7
data bits and two stop bits, The first byte contains “L”, “R” key status and four bits of the two most significant bits
in horizontal counter and vertical counter. The second byte represents the value accumulated by horizontal
counter, the third byte is the data of the vertical counter, The last byte contains “M” key status and Z-axis value.
The vertical data is transmitted in 2’s complement.
Output byte arrange:
