CHAPTER 32 ON-CHIP DEBUG FUNCTION
The on-chip debug function of the V850ES/JG3-H and V850ES/JH3-H 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-H and V850ES/JH3-H, 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.
