Notes On Differences Between The Actual Mcu And Emulator - Renesas M30800T-CPE User Manual

Notes on Differences between the Actual MCU and Emulator:

• Operations of the emulator differs from those of mask MCUs as listed below.
(1) Reset condition
(2) Data values of RAM and ROM areas at power-on
(3) Register values when power is turned on
(4) Internal memory (RAM and ROM) capacity, etc.
(5) MCU function
• As a pitch converter board and other devices are used between the evaluation MCU and the target
system, some characteristics are slightly different from those of the actual MCU. Therefore, be sure
to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your
system and make final confirmation with a CS (Commercial Sample) version MCU.
IMPORTANT
Set the time for starting up (0.2 to 0.8 Vcc) 1µs or less.
When power is turned on, the internal ROM area of the emulator are defaulted to DE
internal RAM area is indefinite (the emulator system does not default this area).
When power is turned on, the emulator's register values default to 0. However, the ISP register
defaults to 500 and the program counter defaults to the reset vector value (FC0000

initialized by the emulator.
Because the internal memories (RAM and ROM) are emulated by the emulation memory, the
capacity and assignment of the emulator's internal memories differ from those of the actual
MCU.
Some MCU functions cannot be used in the emulator system. For details, refer to "Notes on
MCU Functions That Cannot Be Used with This Emulator" (page 11).
