Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

* Programming Sequence for Register Reading/Writing
|
|
==============================================================================
|
|
|
|
Register inversion requirement:
|
|
|
|
Following values needed to be inverted(the '~' operator in C) before being
|
|
sent to FSP:
|
|
|
|
0xe9, 0xee, 0xf2 and 0xff.
|
|
|
|
Register swapping requirement:
|
|
|
|
Following values needed to have their higher 4 bits and lower 4 bits being
|
|
swapped before being sent to FSP:
|
|
|
|
10, 20, 40, 60, 80, 100 and 200.
|
|
|
|
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. if the register address being to read is not required to be
|
|
inverted(refer to the 'Register inversion requirement' section),
|
|
goto step 6
|
|
|
|
5a. send 0x68 PS/2 command to FSP;
|
|
|
|
5b. send the inverted register address to FSP and goto step 8;
|
|
|
|
6. if the register address being to read is not required to be
|
|
swapped(refer to the 'Register swapping requirement' section),
|
|
goto step 7
|
|
|
|
6a. send 0xcc PS/2 command to FSP;
|
|
|
|
6b. send the swapped register address to FSP and goto step 8;
|
|
|
|
7. send 0x66 PS/2 command to FSP;
|
|
|
|
7a. send the original register address to FSP and goto step 8;
|
|
|
|
8. send 0xe9(status request) PS/2 command to FSP;
|
|
|
|
9. the response read from FSP should be the requested register value.
|
|
|
|
Register writing sequence:
|
|
|
|
1. send 0xf3 PS/2 command to FSP;
|
|
|
|

|
|
inverted(refer to the 'Register inversion requirement' section),
|
|
goto step 3
|
|
|
|
2a. send 0x74 PS/2 command to FSP;
|
|
|
|
2b. send the inverted register address to FSP and goto step 5;
|
|
|
|
3. if the register address being to write is not required to be
|
|
swapped(refer to the 'Register swapping requirement' section),
|
|
goto step 4
|
|
|
|
3a. send 0x77 PS/2 command to FSP;
|
|
|
|
3b. send the swapped register address to FSP and goto step 5;
|
|
|
|
4. send 0x55 PS/2 command to FSP;
|
|
|
|
4a. send the register address to FSP and goto step 5;
|
|
|
|
5. send 0xf3 PS/2 command to FSP;
|
|
|
|
6. if the register value being to write is not required to be
|
|
inverted(refer to the 'Register inversion requirement' section),
|
|
goto step 7
|
|
|
|
6a. send 0x47 PS/2 command to FSP;
|
|
|
|
6b. send the inverted register value to FSP and goto step 9;
|
|
|
|
7. if the register value being to write is not required to be
|
|
swapped(refer to the 'Register swapping requirement' section),
|
|
goto step 8
|
|
|
|
7a. send 0x44 PS/2 command to FSP;
|
|
|
|
7b. send the swapped register value to FSP and goto step 9;
|
|
|
|
8. send 0x33 PS/2 command to FSP;
|
|
|
|
8a. send the register value to FSP;
|
|
|
|
9. the register writing sequence is completed.

(Note that this function has the functionality of bit 1 even when

bit 1 is not set. However, the format is different from that of bit 1.
