Title: METHOD FOR DETECTING AN UNCORRECTABLE ERROR IN A NON-VOLATILE MEMORY OF A MICROCONTROLLER
Abstract:
The present invention relates to a method for detecting and managing an uncorrectable error in a non-volatile memory of a microcontroller, said microcontroller having a read interface (E), an exception manager (X), and a set of internal registers and execution parameters that form a low-level context of said microcontroller. The method provides for backing up (X1) the low-level context of the microcontroller, as well as restoring (X2) said context in the event that an exception (HW_X) is raised during an attempt (E2) to read data from the non-volatile memory, provided that a specific strategy for detecting and managing an uncorrectable error is activated (E1).
