Enable the PM code's memory area checksum over sleep. This option

will generate CRCs of all blocks of memory, and store them before

going to sleep. The blocks are then checked on resume for any

errors.

Set the chunksize in Kilobytes of the CRC for checking memory

the CRC data block will take more memory, but wil identify any
