Operation
The M41T00AUD clock operates as a slave device on the serial bus. Access is obtained by
implementing a start condition followed by the correct slave address (D0h). The 10 bytes
contained in the device can then be accessed sequentially in the following order:
The M41T00AUD continually monitors VCC for an out of tolerance condition. Should VCC fall
below VPFD, the device terminates an access in progress and resets the device address
counter. Inputs to the device will not be recognized at this time to prevent erroneous data
from being written to the device from an out of tolerance system. When VCC falls below VSO,
the device automatically switches over to the backup battery or capacitor and powers down
into an ultra low current mode of operation to conserve battery life. Upon power-up, the
device switches from battery to VCC at VSO and recognizes inputs.
