630 Programming Sequence for Page Register Reading
631 ==============================================
632
633 In order to overcome the limitation of maximum
634 supported, the hardware separates register int
635 'pages.' Each page is able to include up to 25
636
637 The default page after power up is 0x82; there
638 access to register 0x8301, one has to use foll
639 to page 0x83, then start reading/writing from/
640 the register read/write sequence described in
641
642 Page register reading sequence:
643
644 1. send 0xf3 PS/2 command to FSP;
645
646 2. send 0x66 PS/2 command to FSP;
647
648 3. send 0x88 PS/2 command to FSP;

650 4. send 0xf3 PS/2 command to FSP;
