Hi,
Does the Bus Encryption Engine encrypt as well as decrypt?
For example, if I was running an Encrypted XIP application (from serial nor flash), and I wanted it to write something to a different area of flash, what happens? Is it encrypted when writing, and decrypted when reading? Or are all read/writes to flash in plaintext, and only reads of the bootable image decrypted on the fly?
Many thanks.
Hello,

No, the BEE is implemented as an on-the-fly decryption engine only.
Have a great day,
Victor
