CHAPTER 4 MEMORY BANK SELECT FUNCTION (
PD78F0536, 78F0537, AND 78F0537D ONLY)
Remark
Note the following points to use the memory bank select function efficiently.
• Allocate a routine that is used often in the common area.
• If a value that is planned to be referenced is placed in RAM, it can be referenced from all of the areas.
• If the reference destination and the branch destination of the routine placed in a memory bank are
placed in the same memory bank, then the code size and processing are more efficient.
• Allocate interrupt servicing that requires a quick response in the common area.
