The successful application of the software in practical oil station shows the scheme is reasonable. So, there is good value to other serial communication fields.
The two methods can be enabled concurrently. The serial interrupt scheme typically associated with Distributed DMA is also supported.
这二种方法可以同时存在。通常与“分布式dma”相关联的“串行化中断”也被支持。

Then the design of the RS-422 serial communication module is introduced in detail, including the whole scheme of serial communication module and the design of functional circuit.
