2.1.3 Stack pointer (SP)
This is a 16-bit register that holds the start address of the memory stack area. Only the internal high-speed
RAM area can be set as the stack area.
Figure 2-3. Stack Pointer Configuration
The SP is decremented ahead of write (save) to the stack memory and is incremented after read (reset) from
the stack memory.
Each stack operation saves/resets data as shown in Figures 2-4 and 2-5.
Caution Since RESET input makes SP contents undefined, be sure to initialize the SP before instruction
execution.
