CHAPTER 28 ON-CHIP DEBUG FUNCTION
The V850ES/JG3 on-chip debug function can be implemented by the following two methods.
• Using the DCU (debug control unit)
On-chip debug function is implemented by the on-chip DCU in the V850ES/JG3, with using the DRST, DCK, DMS,
DDI, and DDO pins as the debug interface pins.
• Not using the DCU
On-chip debug function is implemented by MINICUBE2 or the like, using the user resources, instead of the DCU.
The following table shows the features of the two on-chip debug functions.

Notes 1. This is a function which reads out memory contents during program execution.
2. This is a function which rewrites RAM contents during program execution.
