3.11 PARALLEL INTERFACE CIRCUIT
This circuit performs 8-bit parallel interface by mainly using the gate array ports. When the parallel
interface is not used, pull up STB (Pin 52) of the gate array (CBM-202LA) through use of 10KΩ
resistance. Also, either connect CPU's STB (Pin 87) to INTR (Pin 56) of the gate array or pull it up with
10K Ω resistance.
