Note on Access Prohibited Area:
Notes on Stack Area:
Notes on Reset Vector Area:
Even if a user program is not being executed (including when run-time debugging is being performed), the
evaluation MCU keeps running so as to control the emulation probe. Therefore, timers and other components do
not stop running. If a maskable interrupt is requested when the user program is not being executed (including
when run-time debugging is being performed), the maskable interrupt request cannot be accepted, because the
emulator disables interrupts. The interrupt request is accepted immediately after the user program execution is
started.
Take note that when the user program is not being executed (including when run-time debugging is being
performed), a peripheral I/O interruption is not accepted.
With this product, the program is stopped with a loop program to a specific address. Therefore, if a DMA
request is generated while the program is stopped, DMA transfer is executed. However, make note that DMA
transfer while the program is stopped may not be performed correctly. Also note that the below registers have
been changed to generate DMA transfer as explained here even when the program is stopped.
With this product, as the power voltage cannot be change after powering on the user system, the voltage detect
You cannot use internally reserved areas. Write signals to the areas will be ignored, and values read will be
undefined.
With this product, a maximum 8 bytes of the interrupt stack is consumed as a work area. Therefore, ensure the
+8 byte maximum capacity used by the user program as the user stack area. If the interrupt stack does not have
enough area, do not use areas which cannot be used as stack (SFR area, RAM area which stores data, or ROM
area) as work area. Using areas like this is a cause of user program crashes and destabilized emulator control.
With this product, the interrupt stack pointer (ISP) is set at 00500h and used as a stack area after a reset is
released.
Memory in the emulator main unit is always selected as a reset vector area (FFFFCh--FFFFFh) in order to
operate the evaluation MCU in the emulator-dedicated mode. Set the contents of the reset vector area in one of
the following ways.
You can change data in the reset vector area only when the user program is stopped.
Do not access the reset vector area as data. It may not be accessed properly, and the program may not run
properly in the next bus cycle.
(1) DMA0 transfer counter: TCR0
(2) DMA1 transfer counter: TCR1
(1) Download a user program to an area including the reset vector area.
(2) Set the reset vector using a memory window of the emulator debugger etc.
circuit (voltage down detect interrupt, voltage down detect reset, etc.) cannot be used with this product.
