Read
Reads 4-bytes from Fuse or ROM; returns an error if an attempt is made to read any fuses or ROM locations
which are illegal.
Table 5-8.

Table 5-10. Mode Encoding
GenPersonalizationKey
Loads a personalization key into internal memory and then uses that key along with an input seed to generate a
decryption digest using SHA-256. Neither the key nor the decryption digest can be read from the chip. Upon
completion, an internal bit is set indicating that a secure personalization digest has been loaded and is ready to
use by the BurnSecure command. This bit is cleared (and the digest lost) when the watchdog timer expires or the
power is cycled.
This command will fail if Fuse[87] has been burned.
