Run Mode - This is the basic mode of operation.
Wait Mode - The CRC module is operational.
Stop 1 and 2 Modes- The CRC module is not functional in these modes and will be put into its reset
state upon recovery from stop.
Stop 3 Mode - In this mode, the CRC module will go into a low power standby state. Any CRC
calculations in progress will stop and resume after the CPU goes into run mode.
