********************** Typical M68302 Initialization Code********************
* Register Initialized values in ADS board before execution
* USP = 00080000 ISP = 000040000 (Stack pointer not used)
* Set Base Address = $700000
* Now all 68302 on-chip peripherals begin at address $700xxx
* Set System Control Register
