Power-on Debug Specifications

The emulator has a power-on debug function that executes a program immediately
after the evaluation MCU is powered on.
I Power-on Debug Specifications
Power-on debug(*1) is a function using the reset terminal(*2) of the evaluation MCU to verify
execution of a program immediately after the power-on sequence.
Before the power-on debug function can be used, related operations must be completed to
prepare it.
For information on such operations, see the Softune Workbench Operation Manual.
*1 The evaluation MCU must be compatible with the power-on debug function. For more
information, contact the Fujitsu Sales Dept. or Support Dept.
*2 The name of the reset terminal may depend on the model of the evaluation MCU. For
more information, contact the Fujitsu Sales Dept. or Support Dept.
