problem with pci-6533

I need to communicate between two PCI 6533, both use port0_16 as a input channel and port2_16 as an output channel. I don't  know how to make this two device working under handshaking mode ( using ACK & REQ). Could some one help me!! Thanks in advance!!

i'd like to describe the flow more detail:  pcA output a word(16bit) to pcB, and then pcB output another word to pcA, this two operation must be down under the handshaking mode. In 1ms between pcA and pcB , there are 21 word need transfering.  I define 1ms as a single frame, the whole running time is 20,000 frame.
