occasional communication between many devices over a short distance. The flexible I
additional devices to connect to the bus for expansion and system development.
The interface operates up to 100 Kbps with maximum bus loading and timing. The device is capable of
operating at higher baud rates, up to a maximum of the internal bus clock divided by 20, with reduced bus
loading. The maximum communication length and the number of devices connected are limited by a
maximum bus capacitance of 400 pF.

supports complex applications with multiprocessor control and can be used for rapid testing and alignment
of end products through external connections to an assembly-line computer.
