CC1020 signal sending and receiving interface and micro-controller connects are shown as the picture 1.Micro controller uses pins P2.6 , bidirectional synchronous data interface DIO, DCLK connection of P3.4 ,CC1020. The two-way pins of micro-controller isconnected withCC1020 DIO.And it is used to emit and receive data (input and output). DCLK must be connected to an input terminalofthe micro-controller when it provides data. Data output can choose to use separate pins. At this time to the register ,SEP_DI_DO=1 of CC1020 INTERFACE needs beset up.In synchronous mode, LOCK pins are used for data output,DCLK pins are used for asynchronous mode data output and DIO pins are used for the data input. The micro-controller a pins can be used as the locking signal of locked phase loop,namely,LOCK pins signal.When phase locked loop is locked, LOCK pins is logic low PWL. It can also be used as a carrier detection and other internal test signal.
