Communication Principle

Data buffers of type ComBuffer are used to decouple the data transfer between the memory and the serial bus terminal. They may be written or read asynchronously.

The function blocks described later for receiving and sending data (Send Byte, Receive Byte etc.) make use of only the data buffers for data exchange, and are thus independent of the hardware being used. In all cases, a communication block (KL6ControlBC) is called in addition to the send and receive blocks. It handles the data traffic between the data buffers and the hardware with the maximum possible speed in the background.
