| 63 | Enable the PM code's memory area checksum over sleep. This option | |
| 64 | will generate CRCs of all blocks of memory, and store them before | |
| 65 | going to sleep. The blocks are then checked on resume for any | |
| 66 | errors. | |
| 67 | ||
| 68 | Note, this can take several seconds depending on memory size | |
| 69 | and CPU speed. | |

| 78 | Set the chunksize in Kilobytes of the CRC for checking memory | |
| 79 | corruption over suspend and resume. A smaller value will mean that | |
| 80 | the CRC data block will take more memory, but will identify any | |
| 81 | faults with better precision. | |
