Abstract:
To control update of content in a programmable read-only memory in a system, the security status associated with the system is determined, where the security status is one of a secure mode and non-secure mode. In response to detecting that the system is in secure mode, a write to the programmable read-only memory is enabled. In response to detecting that the system is in non-secure mode, a write to the programmable read-only memory is disabled.
