Data Protection When a Power Failure Occurs
When a power failure occurs during writing data to $L or $LD, the data value just
before writing is guaranteed. (The data value just before writing is guaranteed
up to one word from the head (in case of $L) and up to two words from the head
(in case of $LD).) When writing texts or writing multiple words simultaneously
using the [BMOV] Macro command, the data value is not guaranteed.
* Use $LD to access two word data. Check system memory address $s721 to
$s726 to verify whether writing was successful or not.
