Working Principles

The PT7C4563BWEX utilizes an internal oscillator or an external crystal/ceramic resonator to generate clock signals. It keeps track of time by counting these clock signals and updates the time registers accordingly. The alarm and timer functions are programmed by setting the desired values in the corresponding registers. When the alarm or timer condition is met, the IC generates an interrupt signal on the INT pin.
