==============================================================================
* Programming Sequence for Page Register Reading/Writing
==============================================================================
In order to overcome the limitation of maximum number of registers
supported, the hardware separates register into different groups called
'pages.' Each page is able to include up to 255 registers.
The default page after power up is 0x82; therefore, if one has to get
access to register 0x8301, one has to use following sequence to switch
to page 0x83, then start reading/writing from/to offset 0x01 by using
the register read/write sequence described in previous section.
Page register reading sequence:
1. send 0xf3 PS/2 command to FSP;
2. send 0x66 PS/2 command to FSP;
3. send 0x88 PS/2 command to FSP;
4. send 0xf3 PS/2 command to FSP;
5. send 0x83 PS/2 command to FSP;
6. send 0x88 PS/2 command to FSP;
7. send 0xe9(status request) PS/2 command to FSP;
8. the response read from FSP should be the requested page value.
Page register writing sequence:
1. send 0xf3 PS/2 command to FSP;
2. send 0x38 PS/2 command to FSP;
3. send 0x88 PS/2 command to FSP;
4. send 0xf3 PS/2 command to FSP;
5. if the page address being written is not required to be
inverted(refer to the 'Register inversion requirement' section),
goto step 6
5a. send 0x47 PS/2 command to FSP;
5b. send the inverted page address to FSP and goto step 9;
6. if the page address being written is not required to be
swapped(refer to the 'Register swapping requirement' section),
goto step 7
6a. send 0x44 PS/2 command to FSP;
6b. send the swapped page address to FSP and goto step 9;
7. send 0x33 PS/2 command to FSP;
8. send the page address to FSP;
9. the page register writing sequence is completed.
==============================================================================
* Gesture ID
==============================================================================
Unlike other devices which sends multiple fingers' coordinates to host,
FSP processes multiple fingers' coordinates internally and convert them
into a 8 bits integer, namely 'Gesture ID.' Following is a list of
supported gesture IDs:
ID Description
0x86 2 finger straight up
0x82 2 finger straight down
0x80 2 finger straight right
0x84 2 finger straight left
0x8f 2 finger zoom in
0x8b 2 finger zoom out
0xc0 2 finger curve, counter clockwise
0xc4 2 finger curve, clockwise
0x2e 3 finger straight up
0x2a 3 finger straight down
0x28 3 finger straight right
0x2c 3 finger straight left
0x38 palm
============================================================================== ==============================================================================
* Register Listing * Register Listing
============================================================================== ==============================================================================
Registers are represented in 16 bits values. The higher 8 bits represent
the page address and the lower 8 bits represent the relative offset within
that particular page. Refer to the 'Programming Sequence for Page Register
Reading/Writing' section for instructions on how to change current page
address.
