52 | help | |
53 | Enable the PM code's memory area checksum over sleep. This option | |
54 | will generate CRCs of all blocks of memory, and store them before | |
55 | going to sleep. The blocks are then checked on resume for any | |

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