Abstract

Disclosed is a software method providing for initializing data stored in hardware registers when it is determined that this data has become corrupted, due, for example, to operation of a circuit in an environment having high levels of Electromagnetic Interference (EMI).

Reinitialization of Corrupted Register Data

      Disclosed is a software method providing for initializing data
stored in hardware registers when it is determined that this data has
become corrupted, due, for example, to operation of a circuit in an
environment having high levels of Electromagnetic Interference (EMI).

      The Figure is a flow diagram of this method.  With each loop
within the microcode, in step 1, the initialization settings are
checked for correctness.  If these settings are not correct, the
initialization process is repeated in step 2, based on the assumption
that data within the registers has become corrupted.  This
initialization, which is done without affecting the rest of the
system, ensures that the circuit can continue to function properly.
If it is determined in step 1 that the registers have not been
corrupted, the other processes of the system are continued without
the initialization process.
