信道频率
共多信道频率扫描图显示了如何使用两个状态机执行从到的多信道频率扫频的示例（即，在一个信道上扫频，移动到下一个信道，然后重复扫频）在本例中，由于（寄存器，位）和（寄存器位）都是索引的，因此被定义为，因为乘法器滤波器环路内有三个状态，被定义为，因为发射机环路内有四个状态如图所示，•乘法器滤波器状态=休眠（环路外）•乘法滤波器状态=输出至到•乘法员滤波器状态=输出至到•乘法符滤波器状态=输出至到•传输状态=睡眠（环路外的）•传输状态=在信道上传输•传输状态=在信道上传输•发送状态=在信道上传输•传输状态=在信道上传输和上的重置脉冲将两个状态机置于其初始状态，在这种情况下，这被定义为睡眠模式然后，和上的脉冲将两个状态机推进到它们的一活动状态在本例中，跳过初始就绪状态，电路直接从睡眠模式进入活动模式当扫频时
附加脉冲乘法器
在上施加附加脉冲乘法器就绪模式用于确保乘法器滤波器电路的最快切换在信道上完成频率扫描后，和都被脉冲化，以使乘法器滤波器回到其一状态，并且发射机将激活信道从切换到然后，使用引脚上的重复脉冲重复频率扫描在本例中，在对四个信道进行频率扫描后，两个状态机返回到一个活动状态在大型阵列中，建议将它们循环回到睡眠或就绪状态，等待轮到它们再次传输序列器睡眠控制为了进一步简化的控制，可以将两个状态机的睡眠状态链接起来，以便一个序列器进入睡眠状态，另一个也进入睡眠状态此链接有助于限制实现所需操作类型所需状态的总数要使用此功能，必须设置两个睡眠控制位中的一个
Channel frequency
The total multi-channel frequency scanning diagram shows an example of how to use two state machines to perform multi-channel frequency scanning from to (that is, sweep the frequency on one channel, move to the next channel, and then repeat the frequency scanning). In this example, because (register, bit) and (register bit) are indexed, they are defined as, because there are three states in the multiplier filter loop, which are defined as, Because there are four states in the transmitter loop as shown in the figure, • Multiplier filter state=Sleep (out of loop) • Multiplier filter state=Output to • Multiplier filter state=Output to • Multiplier filter state=Output to • Multiplier filter state=Output to • Transmission state=Sleep (out of loop) • Transmission state=Uploading on the channel • Transmission state=Uploading on the channel • Transmission state=Uploading on the channel • Transmission state=Reset pulse transmitted on the channel and put the two state machines in their initial state. In this case, this is defined as sleep mode. Then, the pulse on the and pushes the two state machines to one of their active states. In this example, the initial ready state is skipped, The circuit directly enters the active mode from the sleep mode when sweeping
Additional pulse multiplier
Apply an additional pulse multiplier ready mode on the to ensure that both and are pulsed after the fastest switching of multiplier filter circuit completes frequency scanning on the channel, so that the multiplier filter returns to its state, and the transmitter switches the active channel from to and then, use the repetition pulse repetition frequency scanning on the pin. In this example, after frequency scanning on the four channels, The two state machines return to an active state. In a large array, it is recommended to cycle them back to sleep or ready state, and wait for them to transmit the sequencer sleep control again. To further simplify the control, you can link the sleep states of the two state machines, so that a sequencer can enter the sleep state, The other also enters the sleep state This link helps limit the total number of states required to achieve the desired operation type To use this function, you must set one of the two sleep control bits
