;---------------------- INITIALIZATION HOOK ---------------------------------

;
;     Modifies:
;CPU registers: PS(flags), A, X, Y
;H/W registers: T1
;RAM registers: TEMPR0 - TEMPR9
;
;   Processing: Called after core initialization is completed, and before any
;               system command is executed. Perform custom initialization of
;               RAM variables, GPIOs pins, h/w registers.

;         Exit: Nothing
;
;     Modifies:
;CPU registers: PS(flags), A,
;H/W registers: T1
;RAM registers: TEMPR0 - TEMPR9
;
;   Processing: Called every 5ms by core TimerX ISR. Perform custom polling
;               of KBC/EC GPIO pins. Recommended execution time is 0.5ms or
;               less per call.

;         Exit: Nothing
;
;     Modifies:
;CPU registers: PS(flags), A,
;H/W registers: T1
;RAM registers: TEMPR0 - TEMPR9
;
;   Processing: Called every 5ms by TimerX ISR after core polling of SMBus
;               devices is completed (core polling may be disabled via KBC
;               control variables, if custom Hook is to replace it). Perform
;               custom SMBus polling. Software timer should be implemented
;               in order to prevent sending polling commands too often
;               (recommended - 1/1000ms or less).

;---------------------- EVENT TASK CUSTOM HOOK ------------------------------
;
;        Entry: X = Event Notification Byte (ID)
;
;         Exit: IF C = 1 - ID is completely processed by Hook

;     Modifies:
;CPU registers: PS(flags), A, X(if ID is processed), Y
;H/W registers: T1
;RAM registers: TEMPR0 - TEMPR2, TEMPR6
;
;   Processing: Called as a handler for custom task 92h. Dispatch event ID
;               and process it according to the custom specification.

;                  X = Custom key value (preserved)
;
;     Modifies:
;CPU registers: PS(flags), A, X(if Key is built), Y
;H/W registers: T1
;RAM registers: TEMPR0 - TEMPR9
;
;   Processing: Called by build scan code core routine when custom key is to
;               be processed (custom key values are always in the range of
;               80h-FFh). Provide custom specific build for the respective
;               keys on the Internal Keyboard.
