34.1 Debugging with DCU
chip debug emulator (MINICUBE).

Figure 34-1. Circuit Connection Example When Debug Interface Pins Are Used for Communication Interface
Programs can be debugged using the debug interface pins (DRST, DCK, DMS, DDI, and DDO) to connect the on-
Notes 1. Example of pin connection when MINICUBE is not connected
The interface signals are described below.
(1) DRST
This is a reset input signal for the on-chip debug unit. It is a negative-logic signal that asynchronously
initializes the debug control unit.
MINICUBE raises the DRST signal when it detects V
started, and starts the on-chip debug unit of the device.
When the DRST signal goes high, a reset signal is also generated in the CPU.
When starting debugging by starting the integrated debugger, a CPU reset is always generated.
