Parallel Port

  The 5206 processor chip has two 8-bit parallel ports, Port A and B, Figure 112. These provide a simple way of inputting or outputting bits or bytes to external hardware such as switches, LEDs, or other devices. The parallel port pins are TTL compatible.

HLAB6 explains how to program Port A using assembly or C. In HLABs 7 and 8 you will gain some experience in using Port A by creating a flashing LED display.

Detailed documentation is provided in Section 9 of the Motorola MCF5206 User Manual.
