(7) Writing of debug monitor program
(8) Flash self programming
(9) Emulation of POC function
(10) Operation after reset
(11) Debugging with real machine running without using MINICUBE2
When the debugger is started for the first time, chip erasure and writing of debug monitor program are
performed. The following devices require about a dozen seconds for these operations.
V850ES/JG2, V850ES/JJ2
V850ES/HE2, V850ES/HF2, V850ES/HG2, V850ES/HJ2
V850ES/IE2
If the CPU operating clock setting is changed by the debugger, the debugger rewrites the debug monitor
program. At this time, it takes about a dozen seconds for this operation. When using NEC Electronics
debugger ID850QB, this specification applies when the setting in the Clock area in the Configuration dialog
box.
If a space where the debug monitor program is allocated is rewritten by flash self programming, the debugger
can no longer operate normally.
The POC function of the target device cannot be emulated. Make sure that the power to the target system is
not shut down during debugging.
After an external pin reset or internal reset, the monitor program performs debug initialization processing.
Consequently, the time from reset occurrence until user program execution differs from that in the actual
device operation.
If debugging is performed with a real machine running, without using MINICUBE2, write the user program
using the QB-Programmer. Programs downloaded by the debugger include the monitor program, and such a
program malfunctions if it is not controlled via MINICUBE2.
