Abstract
A reset pin of a non-volatile read/write memory, which stores boot code, is provided with a reset signal in response to a system reset output by a watchdog timer or other external circuitry. The reset signal causes the non-volatile read/write memory to be placed into read mode. Accordingly, even when a system reset occurs while the non-volatile read/write memory is in write mode, a hang state can be avoided since the memory will be reset to read mode before attempting to read boot code for a reboot operation.
