CHAPTER 2 DEPENDENCE FUNCTIONS
Because "POP PS" (1) is an instruction as invalid breakpoint shown in "Notes on GO Command", no break
occurs at three instructions following "POP PS".
And because instruction (3) is the instruction shown in above-mentioned note among three instructions (2),
(3) and (4) following "POP PS", three instructions (4), (5) and (6) following instruction (3) are executed
continuously.
Consequently, the program counter (PC) advances to NOP instruction (7) when the step operation is executed
from the point of "POP PS" instruction (1).
Note:
• Issuing a chip reset during the execution of the user program, the following functions cleared.
- Execution cycle measurement
- Performance measurement
- Data match status of Data watch break
