TIMEKEEPER
Registers
The M41ST85Y/W offers 20 internal registers
which contain Clock, Alarm, Watchdog, Flag,
Square Wave and Control data. These registers
are memory locations which contain external (user
accessible) and internal copies of the data (usually
referred to as BiPORT
TM TIMEKEEPER cells).
The external copies are independent of internal
functions except that they are updated periodically
by the simultaneous transfer of the incremented
internal copy. TIMEKEEPER and Alarm Registers
store data in BCD. Control, Watchdog and Square
Wave Registers store data in Binary Format.
