Programs can be debugged using the debug interface pins (DRST, DCK, DMS, DDI, and DDO) to connect the on-chip
Notes 1. Example of pin connection when MINICUBE is not connected
The interface signals are described below.
(1) DRST
Figure 28-1. Circuit Connection Example When Debug Interface Pins Are Used for Communication Interface
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
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.
2. A pull-down resistor is provided on chip.
3. For flash memory rewriting
