摘要： One embodiment of the present invention includes a microcontroller that enables its on-chip microprocessor to write data into a register of an on-chip programmable analog circuit even though the two circuits may be operating at different frequencies. Specifically, the microcontroller includes a write synchronization circuit that helps facilitate the write operation between these two circuits. For example, the write synchronization circuit is coupled to receive write cycle signals from the microprocessor and is also coupled to receive trigger signals based on a clocking signal received by the programmable analog circuit. Therefore, upon receiving a write cycle signal, the write synchronization circuit has the ability (if needed) to stall the microprocessor's operations until the optimum time for writing data into the register for controlling the programmable analog circuit. As such, the write synchronization circuit dynamically synchronizes the microprocessor's write operation with the programmable analog circuit's optimum timing condition for receiving data.
摘要翻译：本发明的一个实施例包括一个微控制器，使其片上微处理器能够将数据写入到片上可编程模拟电路的寄存器中，即使两个电路可能以不同的频率工作。具体来说，微控制器包括一个写入同步电路，有助于这两个电路之间的写入操作。例如，写同步电路被耦合以从微处理器接收写周期信号，并且还耦合以基于由可编程模拟电路接收的定时信号接收触发信号。因此，在写入周期信号时，写入同步电路具有停止微处理器操作的能力（如果需要的话），直到将数据写入用于控制可编程模拟电路的寄存器的最佳时间。这样，写同步电路使微处理器的写操作与可编程模拟电路的最佳定时条件动态同步，用于接收数据。
