Notes on Connecting the Emulator Debugger
(1) Reset state
Under [Connection] on the [Connection Settings] tabbed page, be sure to select [Yes] for [Hold reset
during connect] (the operation is explained for the case when the e
2
studio is in use).
When [Yes] is selected, during connection to the emulator debugger, the emulator maintains the low-level
output on the RES# pin of the MCU and places the MCU in the OCD mode. However, to start the
operation of the built-in debugging circuits of the MCU, the emulator releases the reset for about 50 msec
while it is connected, and the user program automatically runs during that period.
