=== Century Notes ===
First of, whether or not The DS12887A RTC chip used in the Century is stored at [32h] depends on software. PCs are conventionally using it like so. SYMBiFACE II seems to (try to) do the samedoes not have a century register. Whether the Aleste and Dk'tronics do store the century is unknown - and, if they should do, it might be anywhere at [32h] or elsewhere, in BCD or in binary... or even octal or ascii. The "century" byte at [32h] is battery backed RAM in most chips (DS1287A, DS12887, DS12885, DS12887A), so software must manually adjust it when needed, and software can store BCD or binary or other values. However, during the year 2000 panic, two chips have been hastily produced (DS12C887, DS12C887A) which do automatically "destroy" this RAM location when the year wraps from 00 to 99, according to the datasheet, the destroyed value register is then set to 20h (BCD twenty), and can be accessed only in BCD mode, and RAM at [32h] returns "N/A" in binary mode. The DSE feature is crap, and should be disabled (it's using a hardcoded timezone, and thus works only in a few countries, and, it lacks a flag that indicates if daylight saving time is active or not). SYMBiFACE II Cautions: Incorrectly claims to have 128 bytes battery backed RAM (but actually uses a DS1287A chip with 50 bytes battery backed RAM) (128 byte chips don't exist anyways, the maximum would be 114 bytes). The century is accidently referred to as millennium, it seems to be stored as BINARY value 19 or 20 (which may conflict with the Y2K-panic chips which are only "optimized" for destroying BCD values)unknown.
