ABSTRACT:
A method and apparatus suspend operations in a flash memory in order to read code from the flash memory. A system comprises a processor and a nonvolatile writeable memory coupled together. A non-read operation is preempted in the nonvolatile writeable memory responsive to an input at a pin of the nonvolatile writeable memory. The preemption occurs by either suspending the non-read operation or aborting the non-read operation. Code is read from the nonvolatile writeable memory and provided to the processor. Subsequently, the non-read operation is resumed at where it was suspended, or is started anew.
