Abstract:

PC16550D is the universal asynchronous communication chip made by National Semicondutor Company.To content the requirement of the communication system in real time processing,we can implement high speed serial interface communication of system by universal asynchronous communication chip PC16550D,meanwhile the control ability of system communication interface can be intensified.This paper provides the application features and registers related with communication of PC16550D. The application hardware circuit of communication between ADSP21060 and PC using PC16550 is introduced in detail.This paper also provides an initialization software programme of PC16550D using ADSP21060.
