Clock operation
3.4
Stopping and starting the oscillator
The oscillator may be stopped at any time. If the device is going to spend a significant
amount of time on the shelf, the oscillator can be turned off to minimize current drain on the
battery. The STOP Bit is located at Bit D7 within the Seconds Register (9h). Setting it to a '1'
stops the oscillator. When reset to a '0,' the M48T212V oscillator starts within one second.
Note:
It is not necessary to set the WRITE Bit when setting or resetting the FREQUENCY TEST
Bit (FT) or the STOP Bit (ST).
