Question
a. Develop a time delay procedure for the 3.0 GHz Pentium-Core2 that waits for
50ms
b. The 8255 shown in the following is configured as follows: port A as output, B as
input, and port C (low and high) as output.
1. Find the port addresses assigned to A, B, C and the control register
2. Find the control byte (word) for this configuration.
3. Program the ports to input data from port B and send it to both ports A and
C.
Hint you can use delay in (a) if needed
