WSB-Q354 PICMG 1.0 CPU CardPage 100Î Parallel Port Mode [Normal]Use the Parallel Port Mode option to select the mode the parallel port operates in.Î Normal D EFAULT The normal parallel port mode is the standard modefor parallel port operation.Î EPP The parallel port operates in the enhanced parallelport mode (EPP). The EPP mode supportsbi-directional communication between the systemand the parallel port device and the transmissionrates between the two are much faster than theNormal mode.Î ECP The parallel port operates in the extendedcapabilities port (ECP) mode. The ECP modesupports bi-directional communication between thesystem and the parallel port device and thetransmission rates between the two are much fasterthan the Normal modeÎ ECP+EPP The parallel port operates in the extendedcapabilities port (ECP) mode. The ECP modesupports bi-directional communication between thesystem and the parallel port device and thetransmission rates between the two are much fasterthan the Normal modeThe parallel port is also be compatible with EPPdevices described aboveÎ Parallel Port IRQ [IRQ7]Use the Parallel Port IRQ selection to set the parallel port interrupt address.Î IRQ5 IRQ5 is assigned as the parallel port interrupt addressÎ IRQ7 D EFAULT IRQ7 is assigned as the parallel port interrupt address
