ABSTRACT:
A data processing apparatus and method are described in which a reset function for recovering from a system crash is provided. Upon activation of a reset signal (nRESET), the contents of a program counter (R15pc) are saved within another register (R14svc) prior to the reinitialization of the system. The contents of the register saving the program counter value are preserved through the reset operation to provide information to a person seeking to debug the system as to where a particular problem requiring the reset signal to be initiated occurred within the instruction address sequence.
