Note On Differences Between Actual Mcu And Emulator; Notes On Watchdog Function; Notes On Internal Resources Of Mcu; Note On Software Breaks - Renesas M38000TL2-FPD User Manual

Note on Differences between Actual MCU and Emulator:

• Operations of the emulator differ from those of mask MCUs as listed below.
(1) Reset condition
(2) Initial values of internal resource data at power-on
(3) Interrupt stack pointer after releasing reset
(4) Internal memory (ROM and RAM) capacities, etc.

Notes on Watchdog Function:

• The MCU's watchdog timer can be used only while programs are being executed. To use it
otherwise, disable the watchdog timer.
• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.

Notes on Internal Resources of MCU:

• In the MCU's internal RAM area, single-step and break operations cannot be performed.
• When using the 38000 Series emulator MCU, note that addresses $FFFE and $FFFF cannot be used.
When using any MCU other than the 38000 Series, you cannot use addresses $8000 and $8001.

Note on Software Breaks:

• Software breaks generate break interruptions by forcibly inserting a BRK instruction "00h" instead
of an instruction code. Therefore, when referencing the result of a trace in bus mode, "00h" is
displayed for the instruction fetch address where a software break is set.
IMPORTANT
Therefore, be sure to evaluate your system with an evaluation MCU. Before starting mask
production, evaluate your system and make final confirmation with an ES (Engineering
Sample) version MCU.
