9. A memory system addressed by 20 address lines and popu sized ICs (Call them IC A, B, C, and D) lated by 4 equally a. What is the total b. What is the size of each IC. c. In which of the ICs are these addresses size of this memory system i. 2134H iii. 7FOFH iv. 5555H it take for this TC to fill up? If this TC support clock division (DivisorVal) by 2, 4, 8, and 16, also, you are allowed to set the ScalarVal (Maximum number to which this TC counts, between 1 and 255). What numbers will you use for ScalarVal and DivisorVal to get this TC to fill-up after one millisecond. 10. A 10-bit timer counter (TC) is driven by a 16MHz clock, how much time does
