| help |
| 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. |

| help |
| 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 wil identify any |
| faults with better precision. |
