The visible registers depend on the processor mode • The other registers (the banked registers) are switched in to support IRQ, FIQ, Supervisor, Abort and Undefined mode processing

该文档详细说明了，在使用HCS12X处理器进行编程时，如何将定义的数据类型分配在Direct Addressing Area，extended addressing area，banked addressing area-The present document describes how programmer can help the HCS12X compiler to generate the more optimal cod
