Closely coupled configuration-

enter image description here

Co-processor cannot take control of the bus; it does everything through the CPU.

Closely Coupled processor may take control of the bus independently 8089 shares CPU’s clock and bus control logic.

Communication with host CPU is by way of shared memory.

Host sets up a message (command) in memory.

Independent processor interrupts host on completion.

Two 8086’s cannot be closely coupled.
