Abstract :This paper discusses the termination mode of PCI bus transaction relatively across - the -board1 Either the master or the target may initiate termination of a PCI transaction1The master and the target terminate the transaction and signal different termination condition by combining different signals at the same time1The two types of master initiated termination is normal termination and Master - Abort termination1The three types of target initiated termination are retry ,disconnect and Target - abort.
Key words :PCI bus ;termination mode of transaction ;the master ;the target
