The VCCp pin of the TMS320F240 slave DSP selects the protection
mode of the flash memory and the slave DSP watchdog mode:
n If the jumper connects VCCp to VCC (default setting):
n erase/write operations to the flash memory are enabled
n the watchdog is disabled
n If the jumper connects VCCp to GND:
n erase/write operations to the flash memory are disabled
n the watchdog is enabled
The dSPACE software does not support the watchdog of
the slave DSP. For this reason, do not change the jumper’s
default setting shown above.
