Abstract
A method for managing the reset of a data processor comprises receiving a first software reset instruction to reset software for operating the data processor. A checksum or value in a data storage register is modified according to a first preestablished logical or mathematical operation in response to the first software reset instruction. A software watchdog reset flag is set in response to the first software reset instruction. A reset is identified as a software reset if the software watchdog reset flag is set and if the checksum in the data storage register is modified in accordance with the first preestablished mathematical or logical operation.

A method for managing the reset of a data processor, the method comprising:
- receiving a first software reset instruction to reset software for operating the data processor;
- modifying a checksum or value in a data storage register according to a first preestablished logical or mathematical operation in response to the first software reset instruction,
- setting a software watchdog reset flag in response to the first software reset instruction;
- and
- identifying a reset as a software reset if the software watchdog reset flag is set and if the checksum in the data storage register is modified in accordance with the first preestablished mathematical or logical operation.
A system for managing the reset of a data processor, the system comprising:
- a receiver for receiving a first software reset instruction to reset software for operating the data processor;
