37.5.2 Power Management

The AES will continue to operate in any sleep mode, if it's source clock is running. The AES interrupts can be used to wake up the device from sleep modes. Refer to the Power Manager chapter for details on the different sleep modes.

AES is clocked only on the following conditions:

Whenever there is an APB access for any read and write operation to the AES registers.
When the AES is enabled & encryption/decryption is on.
