;* FUNCTION
;*
;* INT_Initialize
;*
;* DESCRIPTION
;*
;* This function sets up the global system stack variable and
;* transfers control to the target independent initialization
;* function INC_Initialize. Responsibilities of this function
;* include the following:
;*
;* - Setup necessary processor/system control registers
;* - Initialize the vector table
;* - Setup the system stack pointers
;* - Setup the timer interrupt
;* - Calculate the timer HISR stack and priority
;* - Calculate the first available memory address
;* - Transfer control to INC_Initialize to initialize all of
;* the system components.
;*
;* Major Revision:
;*
;* M. Kyle Craig, Accelerated Technology, Inc.
;*
;*
;*
;*
;* CALLED BY
;*
;* Nothing. This function is the ENTRY point for Nucleus PLUS.
