Name and Function ADDRESS BUS: The address bus provides the address to memory (up to 64K B-bit words) or denotes the I/O device number for up to 256 input and 256 output devices. Ao is the least significant address bit. DATA BUS: The data bus provides bi-directional communication between the CPU, memory, and I/O devices for instructions and data transfers. A.
registers and an accumulator. The 6 general purpose registers may be addressed individually or in pairs providing both single and double precision operators. Arithmetic and logical instructions set or reset 4 testable flags. A fifth flag provides decimal arithmetic operation. The 8080A has an external stack feature wherein any portion of memory may be used as a last in/first out stack to store/retrieve the contents of the accumulator, flags, program counter, and all of the 6 general purpose registers. The 16-bit stack pointer controls the addressing of this external stack. This stack gives th.
