Notes:
•
The reason that the checksum is not carried out on suspending and resuming is for
high-speed performance. But, memory corruption check is carried out to check if the RAM
is in error status by any reason.
•
The RAM corruption check is performed by writing fixed data (0x00 to 0xFF) into a fixed
area (256 bytes area) in the RAM prior to performing the check, and the value written in the
RAM is verified at a time of Resume. If an error is detected, warning message for memory
corruption check is issued, and then reset is performed and the OS files are reloaded.
