GL901Rx 1.1
The movement counters are 9-bit 2's complement integers, where the most significant bit appears as a
sign bit in Byte 1 of the movement data packet. The range of values that can be expressed by the
movement counters is -255 to +255. If this range is exceeded, the appropriate overflow bit is set and the
counter is not incremented/decremented until it is reset.

Intellimouse1 Extensions (3D/3B):
Microsoft Intellimouse1 is an extension to the standard PS/2 mouse. This includes support for a total of
three mouse buttons and three axis of movement (right-left, up-down, and a scrolling wheel). These
additional features require the use of a 4-byte movement data packet rather than the standard 3-byte
packet. Since standard PS/2 mouse drivers cannot recognize this packet format, the Microsoft
Intellimouse1 is required to operate exactly like a standard PS/2 mouse unless it knows the drivers
support the extended packet format.
The Microsoft Intellimouse1 operates just like a standard PS/2 mouse (ie, it uses a 3-byte movement
data packet, responds to all commands in the same way as a standard PS/2 mouse, and reports a device
ID of 0x00.) To enter scrolling wheel mode, the host sends the following command sequence:

Notice: If the device doesn’t support IntelliMouse then it will return 0x00 (Device ID) after the host issues the "Get device ID"
command (0xF2)

Z Movement is a 2's complement number that represents the scrolling wheel's movement since the last
data report. Valid values are in the range of -128 to +127.
