Caution Points:
1. PT7C4563BQ uses 8 bits for address. For excess 0FH address, PT7C4563BQ does not respond. 2. Alarm interrupts flag bits. 3. Alarm interrupt enable bits. 4. Oscillator fail indicates. Indicate clock integrity. 5. Alarm enable bit. Alarm is active when related time is matching if AE = 0. 6. All bits marked with "×" are not implemented. PT7C4563BQ
