E30A Emulator User's Manual
Note on the Lock Bits for the MCU Internal Flash ROM:
The lock bits for the blocks whose contents have been altered by downloading a user program or
setting software breakpoints are in an unlocked state.
Note on Protect Bit 2 (PRC2):
Protect bit 2 (PRC2) behaves in such a way that when the bit is set to 1 to remove write protect and
then a write to any address is executed, the bit is write protected again. Note that the bit cannot be
cleared by a software operation while single-stepping a program or manipulating the memory window.
Note on RDY# Input:
Be sure to input "L" to pin RDY# of the user system during the user program executing (when the RUN
status LED is lit). Inputting "L" to pin RDY# during the user program stopping may cause a malfunction
of the emulator.
Note on HOLD# Input:
Be sure to input "L" to pin HOLD# of the user system during the user program executing (when the RUN
status LED is lit). Inputting "L" to pin HOLD# during the user program stopping may cause a malfunction
of the emulator.
Note on the MCU Used in Debugging:
During debugging, the MCU's internal flash ROM is frequently rewritten as a user program is
downloaded or software breakpoints are set or cleared. Do not use any MCU in product once it was
used in debugging.
Note on Final Evaluation:
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.
