ing a power failure. If the power failure extends
the life of the battery, the microcontroller should
perform the initialization sequence (as described
on page 2-4), and use the SETD command to set
the date and time.
To keep power consumption low during power-
down mode, the RESET, MWCS, MWCLK and
MWDIN signals should be held above V
or below V
