Answer 1

To read register 9 and write the value 171 to register 9, set the appropriate inputs to binary values.

Step-by-step explanation:

To read register 9 and simultaneously write register 9 with the value 171₁₀, we need to set the W_data (write data) input to 171₁₀ in 8-bit binary. The W_addr (write address) input should be set to 9 in 4-bit binary. The W_en (write enable) input should be set to 1 to enable writing to register 9.

For the read operation, the R_addr (read address) input should also be set to 9 in 4-bit binary. The R_en (read enable) input should be set to 1 to enable reading from register 9.
