Illegal opcode reset
In order to provide enhanced robustness to the device against unexpected behavior, a
system of illegal opcode detection is implemented: a reset is generated if the code to be
executed does not correspond to any opcode or prebyte value. This, combined with the
Watchdog, allows the detection and recovery from an unexpected fault or interference.
A valid prebyte associated with a valid opcode forming an unauthorized combination does
not generate a reset.
