QUESTION 1 4MHz LD B, 250 LOOP: DEC B JP NZ, LOOP Calculate the delay time or the program above (answer in uSec). QUESTION 2 If the counter in program #1 is loaded with o instead of 250, the delay loop would be executed times. (5 Points) QUESTION 3 In the program shown below, calculate COUNT, so that the delay time is 250 mSec (clock frequency is 2 MHz) (20 Points). LD DE. CoUNT NEXT DEC DE LD A, E OR D JP NZ, NEXT QUESTION In Problem 2, the purpose of the LD A, E and OR D instructions are? (5 Points) OA. To add TStates to the delay loop. 0 B. To affect flags. OC. To test for D and E 0. OD. Both B and C QUESTION5 If CY 0 and A E8H initially, how many times must the RRCA instruction be executed in order for the CY to be 1? (5 Points)
