Notes on EMEM Dialog Box:
Notes on Address-Match Interrupts:
Notes on the Watchdog Function:
Observe the following when setting up EMEM dialog box of the emulator debugger.
(1) Debug Monitor Bank Address
(2) Processor Mode
Do not single-step an address where an address-match interrupt occurs.
When using an address-match interrupt, do not select the check box of "Enable the Address Match Interrupt
Break Function" in the MCU tab of the Init dialog box. When not using an address-match interrupt, select the
check box.
When you use address-match breaks, if a low reset is input during a user program execution, a debug monitor
program (about 100 cycles) is executed after a reset is released. Take note that it has effects on the user program
execution time and the result of a trace.
When using the watchdog function of the MCU, check the box of “Debug the program using the watchdog
timer” in the MCU tab of the Init dialog box. If this check box is selected, while the user program remains idle
the emulator is performing refresh processing (by writing to the watchdog timer start register) within the
emulator control program. If this check box is unselected, the emulator may run out of control after the user
program has stopped.
When not using the watchdog function of the MCU, do not select the box of “Debug the program using the
watchdog timer”. If this check box is selected, while the user program remains idle the emulator is performing
refresh processing (by writing to the watchdog timer start register) within the emulator control program, and the
watchdog timer starts. If the user program is reexecuted, the watchdog timer underflows generating a watchdog
timer interrupt or a reset.
If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.
When "E0" is specified, 64 KB of area starting from E00000h are allocated for use by the debug monitor.
The 64 KB allocated for the debug monitor cannot be used.
The below areas cannot be set for the debug monitor.
1) MCU internal resources (ROM/RAM/SFR area)
2) Multiplex area
3) Interrupt vector area
It is not possible to view or set the content of the specified area. Even on the memory window or in the
reverse assemble area of the program/source windows, the content of this area is not displayed correctly
though it can be displayed.
Set a processor mode for the target MCU.
To set single-chip mode or memory expansion mode, pin CNVSS used with MCU status must be "L". MCU
status indicates pin level of the user system.
To set memory expansion mode, pins RDY# and HOLD# used with MCU status must be "H".
When the user system is not connected, all modes are available.
