These pins are reset during a Master Reset. Serial Output pins: Composite serial data output to the communications link (peripheral MODEM or data set )the SOUTO S0 SOUT1 signal is set to the marking(logic 1)state upon a Master Reset operation Data Bus D0—D7: Tri-State® bus provides bi-directional communications between the UART and the CPU Data control words and status information are transferred via the D0-D7 Data bus Parallel Port Data Bus: Bi-directional data port which provides parallel input and output to the system. The eight lines are hold in a high-impedance state when LPTOE is high Line printer Strobe: Output line when active (low) provides the line printer with a signal to latch the data currently on the parallel port data bus Line printer Auto Teed: Output line when active (low) provides signal for the line printer to auto feed continuous form paper Line Printer Initiallze : Output line to printer when active (low) signal the line printer to begin an initialization routine Line printer Select :Output line when active (low)selects the printer Parallel Port Interrupt :Tri-State® output (enable by bit 4 of the Printer Control Register ) goes active on the positive transition of ACK*. This interrupt is reset low upon a reset operation or after pending interrupts are serviced Line Printer Error :Input line from the line printer informs the parallel port of an error by inputting an active low signal Set low by the printer upon a deselect condition PE or other error condition Line Printer Select :input from the line printer that goes high when the line printer has been selected Line Printer Busy :input from the line printer that goes high when the line printer has an operation in progress Paper Empty :input form the line printer goes high when the printer is out of paper Printer Acknowledge :input form line printer that goes low to confirm the data transfer from the MS16C552 to the printer was successful. This input control INT2 pin directly. Line Printer Output Enable: When low this input signal enables the parallel port data bus as output. When high the parallel port data bus pins are hold in a high impedance state. For normal line printer operation, this line may be permanently grounded. 7 408-432-9100/www.impweb.com © 2002 IMP, Inc.
