E8a Emulator
7. Notes on Using the E8a Emulator
(3) Debugging in stop mode or wait mode
When debugging in stop mode or wait mode, do not operate windows until the program stops at the breakpoint by
setting the breakpoint at the line of the program which will be executed after the stop mode or wait mode is
cancelled. In addition, disable the automatic update in the watch window or fix the display in the memory window
before running the program so memory accesses do not occur during an execution.
When the program is forcibly stopped or when the memory is referred to or modified in stop mode or wait mode,
these mode will be cancelled.
(4) Note on debugging at less than 2.7V
As flash rewrite occurs when the operations below are executed, if the operating voltage of the MCU is less than
2.7V, do not perform these operations:
- Downloading the user program
- Setting and canceling PC breaks (Setting/canceling event breaks are available)
- Rewriting the value of the Flash memory in the memory window
(5) Note on the CPU clock
Do not use the CPU clock at less than 15.6 kHz (low-speed OCO divided by 8).
(6) Low-current-consumption read mode
When debugging in low-current-consumption read mode or the state that the flash memory is stopped, do not
operate windows until the program stops at the breakpoint by setting the breakpoint at the line of the program which
will be executed after each mode or state is cancelled.
