6.8 KMU — Key management unit
The key management unit (KMU) enforces access policies to a subset region of user information
configuration register (UICR). This subset region is used for storing cryptographic key values inside the key
slots, which the CPU has no access to.
In total there are 128 key slots available, where each key slot can store one 128-bit key value together with
an access policy and a destination address for the key value. Multiple key slots can be combined in order
to support key sizes larger than 128 bits. The access policy of a key slot governs if and how a key value can
