Clock operation
M41T66
3.1
TIMEKEEPER registers
The M41T66 offers 16 internal registers which contain clock, calibration, alarm, watchdog,
flags, and square wave. The clock registers are memory locations which contain external
(user accessible) and internal copies of the data (usually referred to as BiPORT
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.
The internal divider (or clock) chain will be reset upon the completion of a WRITE to any
clock address (00h to 07h).
The system-to-user transfer of clock data will be halted whenever the address being read is
a clock address (00h to 07h). The update will resume either due to a stop condition or when
the pointer increments to a non-clock address.
TIMEKEEPER and alarm registers store data in BCD format. calibration, watchdog, and
square wave bits are written in a binary format.
