RSTC (Reset clock cycle selection)
This option allows you to select the number of CPU cycles applied during the
RESET phase and when exiting HALT mode. You can choose between 4096 CPU
cycles and 256 CPU cycles .
VD (Voltage detection)
This option allows you to enable the voltage detection block (EVD only) with a
selected lowest threshold for the LVD and AVD (VDD ~3v). This option is available
only for packages having EVD pin (80 & 64 pins).The options available are:
•
•
Refer to
information.
WDG.HALT (Watchdog halt)
There are two options: Reset or No Reset . If this option is set to Reset , when the
Watchdog is enabled and a Halt instruction is encountered in the executable code,
a chip reset will be performed. If this option is set to No Reset , no chip reset will be
performed.
WDG.SW (Watchdog)
This option allows you to choose whether the watchdog timer is enabled by
software or by hardware.
Refer to the datasheet of your target ST7 MCU for more information on the
watchdog timer.
Emulation functional limitations and discrepancies
•
•
•
EVD_off — EVD is disabled.
EVD_on — EVD is enabled
All evolutions of discrepancies according to the hardware used are available in
a specific window of the debugger. You can access to this information in ST7
Visual Develop’s Emulator discrepancies dialog box under Emulator menu.
In reference to the option
-
Power supply configuration of the ST7 DVP3 can be either 3.3 V or 5 V through
the SW1 switch located on the ST7-DVP3 MEB (DB352). Consequences on
Port I/Os are the following:
The LVD option is always turned off in HALT/Active HALT mode, no matter
what the selected VD option is.
