* PS/2 Command Set
==============================================================================
FSP supports basic PS/2 commanding set and modes, refer to following URL for
details about PS/2 commands:
http://www.computer-engineering.org/index.php?title=PS/2_Mouse_Interface
==============================================================================
* Programming Sequence for Determining Packet Parsing Flow
==============================================================================
1. Identify FSP by reading device ID(0x00) and version(0x01) register
2. Determine number of buttons by reading status2 (0x0b) register
buttons = reg[0x0b] & 0x30
if buttons == 0x30 or buttons == 0x20:
# two/four buttons
Refer to 'Finger Sensing Pad PS/2 Mouse Intellimouse'
section A for packet parsing detail(ignore byte 4, bit ~ 7)
elif buttons == 0x10:
# 6 buttons
Refer to 'Finger Sensing Pad PS/2 Mouse Intellimouse'
section B for packet parsing detail
elif buttons == 0x00:
# 6 buttons
Refer to 'Finger Sensing Pad PS/2 Mouse Intellimouse'
