Functional limitations and discrepancies
Some MCU’s may present specific limitations and discrepancies. You will find
information specific to your MCU and your hardware configuration in STVD7’s
Discrepancies window. For more information refer to the STVD7 User Manual

Emulation of ports G and H
•
We strongly recommend that you power-on your application board AFTER you are in
debug mode in STVD7, to avoid any damage to your application board owing to these
ports being set high by default.
Debugging TLI routines
•
The LVD option is always turned off in HALT/Active HALT mode, no matter
what the selected VD option is.
The LVD thresholds for VDD rise and VDD fall are not compliant with the last
version of the datasheet (revision 1.4) for the ST72(F)521/321/324 emulator
chip.
The ports G and H are reconstituted by a PLD on the emulator. As soon as you
turn on the emulator, these ports are set high by default — even before you
enter into debug mode in STVD7. However, once you enter into debug mode
(with or without your program running), the values of these ports return to low
level until your program instructs otherwise.
The initialization of these ports doesn’t occur until you enter into debug mode
in STVD7. This means that before you even begin to run your program, these
ports are active.
The TLI interferes with the internal emulator breakpoint interrupt system. Using
a breakpoint (instruction or data) to debug a TLI routine hangs STVD7 and
then is not allowed. We recommend that you use another interrupt to debug
your TLI routine.
