STACK OVERFLOW DETECTING METHOD AND STACK UNDERFLOW DETECTING METHOD

摘要

PROBLEM TO BE SOLVED: To unnecessitate debugger setting at the time of using a detection function and to unnecessitate the update of break conditions even when the break conditions are changed by frequent program correction in debugging. SOLUTION: When executing a program, a stack overflow detection address and stack pointer address preset to a stack overflow register 1 and a stack pointer register 2 are compared and in the case of coincidence, an interruption request is generated and the debugger executes break processing while using a leading address 6a of break processing preset to an overflow interruption vector area 6b.
