31.2.11 Flash Read Protect Features

Flash read protection features are for the security of protected information. There are two types of read protection:

  1. Reads to a page locked via CRP and cannot be read until the next reset. This typically refers to boot code including those done by the Boot ROM.
  2. Device families that have an HSM option. Note that reads to a VSS page can only be accessed by the HSM.

Read protection controlled by the Flash system is directly protected within Flash system and does not require setup external to the FCR.
