5.7. Clock Module
Clock control chip: 8563 T
32768 HZ: 8563 T reset the clock
Battery: External Battery, normal voltage 3.3 V
Diodes (DG1, DG2, DG3) : DG1 connects to 3.3 V voltage, DG2, DG3
Battery are connected at one end, when the mainboard electricity, DG2,
DG3 globe, DG1 conduction, Battery don't power supply; When the
mainboard power cuts, in turn, the Battery power supply, DG2, DG3
conduction, DG1 deadline
