AT123S is a PCI arbiter. It allows users to extend sys-
tem PCI devices or slots without piecing additional cir-
cuit to simply design complexity and increase system
stability. AT123S also provides STOP# input pin with
that extended PCI devices is able to instruct the PCI
master to prematurely end the transaction on the current
data phase same as one defined in PCI specification.
