ABSTRACT:
An improved serial communications circuit, which includes support for Infra Red communications over a number of incompatible IR protocols is provided. To improve serial throughput, and reduce the overhead required of a Central Processing Unit, separate Transmit and Receive FIFO's are provided to buffer incoming and outgoing serial data. These FIFO's are controlled by a state machine which can adjust interrupt requests to the CPU based on the contents of the FIFO's and the time elapsed between interrupt service requests. In addition an improved multi-mode Infra Red modulation and demodulation system is provided which may support, alongside standard hard wired serial communications, wireless IR communications with personal information managers, laptop and palmtop computers, and other personal and professional electronic equipment which may employ an IR remote control.
