Note On Mcu Functions That Cannot Be Used With This Emulator - Renesas M30800T-CPE User Manual

Note on MCU Functions That Cannot Be Used with This Emulator:

• The following MCU features cannot be used with this emulator.
(1) Debugging cannot be done with this emulator in the memory expansion mode or micropro-
(2) Oscillation circuits that use a resonator cannot be used.
(3) Watchdog timers cannot be used.
(4) Single step interrupts (debug interrupt) cannot be used.
(5) The BRK2 interrupt (debug interrupt) cannot be used.
(6) Software reset function cannot be used.
(7) A-D input group select function is unusable.
(8) MCUs with more than 10 KB of internal RAM cannot be debugged.
(9) Flash memory and EPROM modes are not emulated.
IMPORTANT
cessor mode.
This emulator is specifically designed for use in the single-chip mode. For this reason,
debugging is not possible in the memory expansion mode or microprocessor mode.
• When using this emulator, normally set the processor mode bit in the processor mode register
to the "single-chip mode".
• When using this emulator, set the CNVSS and BYTE pins to "L" level.
Because a control gate array is situated between the evaluation MCU and the target system,
oscillation circuits that connect a resonator between the X
The same applies to the sub-clock oscillation circuit (X
resonator cannot be used. See "3.5 Selecting Clock Supply" (page 29).
MCU watchdog timers can only be used during program execution (free running). Disable
watchdog timers in all other program operations (break, dump, forced stop, etc.). However,
under the condition below, it is not possible to use the program execution.
• When setting the watchdog timer selection bit (CM06) of the system clock control register
0 to "1".
Also, if the target system has a watchdog timer in its reset circuit, disable it, too, when using
the emulator.
Single step interrupts cannot be used. The vector address of a single step interrupt is normally
indicated in the emulator work area, and the vector address value cannot be changed.
The BRK2 interrupt cannot be used. The vector address of the BRK2 interrupt is normally
indicated in the emulator work area, and the vector address value cannot be changed.
Do not use the software reset function.
The A-D input group select function (M16C/80T Group-only function) cannot be used.
Because this product incorporates an MCU of a 10KB internal RAM version, MCUs whose
internal RAM size exceeds 10 KB cannot be debugged. The reserved internal area (002C00
through 007FFF ) cannot be used either.
