5.1 Hardware AES Acceleration

Certain MSPM0 devices include hardware acceleration for the advanced encryption standard (AES). There are two types of AES accelerator, named Section 5.1.1 and Section 5.1.2, defined in MSPM0 devices, with different feature set supported. See Table 5-1for comparison of AES and AESADV.

See the device-specific data sheet to determine if a particular device includes hardware AES acceleration.
