Consider Your Computer with memory-mapped I/O. Assume there is no direct memory access (DMA) on your microcomputer. For this problem, we specify four classes of devices: processor, RAM, ROM, and I/O.
a) List the devices that can drive the address bus during a CPU read cycle.
b) List the devices that can drive the address bus during a CPU write cycle.
c) List the devices that can drive the data bus during a CPU read cycle.
d) List the devices that can drive the data bus during a CPU write cycle.
e) List the devices that can drive the R/W line during a CPU read cycle.
f) List the devices that can drive the R/W line during a CPU write cycle.
g) List the devices that can receive the information from data bus during a CPU read cycle.
h) List the devices that can receive the information from data bus during a CPU write cycle.
