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

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