Question

The system in Figure 6–87 requires two code converters. The BCD-to-binary converter changes the 2-digit BCD number in Register A to an 8-bit binary code (actually only 7 bits are required because the MSB is always 0). Use appropriate fixed-function IC code converters to implement
the BCD-to-binary converter function and draw a complete logic diagram including pin numbers.
