(2) Securement of stack area for debugging
In the internal RAM space of the target device, the shaded portion in Figure 5-16 are the area where the debug
monitor program uses as the stack area (5 bytes). Since this area is allocated immediately before the stack
area that is used by the user program, the address of this area varies depending on the stack increase and
decrease. Therefore, the stack pointer must be set by making allowances for the stack size (5 bytes) used for
debugging.
The following figure illustrates the case where the stack area is increased when the internal high-speed RAM
starts from 0xFE00.
