Prototyping Area

The prototyping area provides blocks for connecting the address and data lines, and ports P2, P3, P5, P6, P7, P9 and P20. Refer to DIP Switches for the pin-out of the CPU and bus signals.

Note

• All microcontroller signals are brought out to pins and are driven directly by the microcontroller. Exercise caution to avoid overloading these signal lines.

• Since the MCBx51 supports both the Page mode and Non-page mode you should connect memory-mapped devices directly to the data bus DB0-DB7 and A0-A15.
