GenPersonalizationKey
This command generates a decryption digest that will be used by the subsequent command (LoadSram) to decrypt the key
value that is to be written into the SRAM. This command must be run immediately prior to LoadSram within the same
watchdog cycle.
This command loads a transport key from an internal secure storage location and then uses that key along with an input seed
to generate a decryption digest using SHA-256. Neither the transport key nor the decryption digest can be read from the chip.
Upon completion, an internal bit is set indicating that the decryption digest has been generated and is ready to use by
LoadSram. This bit is cleared (and the digest lost) when the watchdog timer expires, the chip goes to sleep or the power is
cycled.
