Description (partial)

Very unusually the isolated DSP reboot feature can fail to work on a 5300 series MCU. This means that a single DSP restarting unexpectedly can cause the whole unit to restart unexpectedly.

When a DSP restarts unexpectedly on a 5300 it can cause other DSPs to restart. Occasionally this will be interpreted as a situation where the whole unit should restart. This only happens in 4.5(1.45) software.
