450 Enable the PM code's memory area checksum over sleep. This option
451 will generate CRCs of all blocks of memory, and store them before
452 going to sleep. The blocks are then checked on resume for any
453 errors.

455 Note, this can take several seconds depending on memory size
456 and CPU speed.

465 Set the chunksize in Kilobytes of the CRC for checking memory
466 corruption over suspend and resume. A smaller value will mean that
467 the CRC data block will take more memory, but wil identify any
468 faults with better precision.
