现在用TMS320F28027芯片,由于程序比较大, 0x008000-0x009000 这个空间不够用,能不能把一部分程序放到0x3f8000-0x3f9000中呢?非常感谢

Seven Han:Program space. On the C2xLP CPU, program space could be mapped anywhere from (0x0−0xFFFF).
With the extended address reach of the C28x (22 bits), the compatible region in program space for the
C2xLP is 0x3F0000−0x3FFFF. Thus, any program memory on the C2xLP must be remapped to this upper
region on the C28x. When the processor accesses program memory, the upper bits (bits 16−22) will be
forced to all 1’s when C2xLP- compatible instructions are used (See Appendix E).
