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 -1-13794474344白生 1 page VC8563 Figure 4: IDD as a function of T; CLKOUT = 32KHz Figure 5: Frequency deviation as a function of VDD Application Information Register Organization The VC8563 contains 16 registers with an auto-incrementing address register as shown on Table1.

Bit positions labeled with 0 should always be written with logic 0. All 16 registers are designed as addressable 8-bit parallel registers although not all bits are implemented. The first two registers (00H and 01H) are used as control and status registers. Registers 02H to 08H are used as counters for clock function (seconds up to year’ counters). Registers 09H through 0CH contain alarms -5-13794474344白生 5 Page VC8563 Figure 12.
