370 | ============================================================================== | |
371 | ||
372 | Register inversion requirement: | |

375 | sent to FSP: | |

378 | ||
379 | Register swapping requirement: | |

382 | swapped before being sent to FSP: | |
383 | ||
384 | 10, 20, 40, 60, 80, 100 and 200. | |

455 | swapped(refer to the 'Register swapping requirement' section), | |
456 | goto step 8 | |
457 | ||
458 | 7a. send 0x44 PS/2 command to FSP; | |
459 | ||
460 | 7b. send the swapped register value to FSP and goto step 9; | |
