0000H - 03FFH 

F000H - F3FFH 

FC00H - FFFFH 

A type of interrupts

An input signal at the microprocessor chip

Used for DMA opeartions

Used to synchronize slow peripherals with the microprocessor  

LED connected with IO port

One bit of the accumulator

Flip-flop inside the ALU

Memory-mapped uses 8-bit addresses, peripheral mapped uses 16-bit addresses

Memory-mapped uses 16-bit addresses, peripheral mapped uses 8-bit addresses

Memory-mapped uses IN and OUT instructions, peripheral mapped uses same memory instructions

No difference, both uses the same control signals
