Register 108: CRC and Cryptographic Modules Run Mode Clock Gating Control
(RCGCCCM), offset 0x674
The RCGCCCM register provides software the capability to enable and disable the CRC and
Encryption Modules ( AES, DES, and SHA/MD5) in Run mode. When enabled, the modules are
provided a clock and accesses to module registers are allowed. When disabled, the clock is disabled
to save power and accesses to module registers generate a bus fault.
Important: This register should be used to control the clocking for the CRC, AES, DES, and
SHA/MD5 modules.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
