System Bus
The system bus is CON5. It contains 16 data lines (D0-D15), 8 address lines (A0-A6, A24), and
some control signal lines (such as chip select, read/write, reset and so on). CON5 can provide 5V
output. In fact very few users would extend interfaces through system bus. Below is the detailed
information about CON5’s pins.
