The number of days in each month and leap years are automatically adjusted. The clock can operate in two modes: one is the 12-hour mode with an AM/PM indicator，the other is the 24-hour mode. The clock/calendar is full binary-coded decimal (BCD). In addition, the VC8563 contains a programmable clock output, timer, an alarm, a voltage-low detector. All address 2 and data are transferred serially via I C bus and The VC8563 operates as a slave device on the serial bus. The built-in word address register incremented automatically after each written or read data byte. The VC 8563 is designed to operate on very low power consumption. a is Block Diagram -1-13...
