4.2.7 Cautions on debugging
86
(1) Handling of device that was used for debugging
(2) Overwriting flash memory during on-chip debugging
(3) Software break (1)
(4) Boot swapping during self programming
This section describes cautions on performing on-chip debugging for a 78K0 microcontroller.
Be sure to read the following to use MINICUBE2 properly.
Do not mount a device that was used for debugging on a mass-produced product, because the flash memory
was rewritten during debugging and the number of rewrites of the flash memory cannot be guaranteed.
If the following operations are performed during on-chip debugging, the flash memory in the device is
overwritten.
<1> Downloading a program
<2> Manipulation in Memory Fill dialog box
<3> Manipulation in Memory Copy dialog box
<4> Manipulation to change memory in Memory window
<5> Online assembly in Assemble window
<6> Settings when using software breaks
<7> Program execution or software reset operation, while ″ Permit ″ has been selected for the Target Power Off
<8> Operation that uses pseudo real-time RAM monitor function
It takes time from completion of flash memory programming until the control is passed to GUI.
During program running, do not rewrite the data at the address where a software break is set. This includes
self programming and rewriting to RAM. If performed, the instruction placed at the address may be invalid.
The boot swapping function cannot be emulated. This is because boot swapping moves the memory spaces
used for debugging, and thus the debug communication can no longer be performed.
