Parallel printer port Data bit 6.
UART Serial Data Output.
Parallel printer port Data bit 5.
Parallel printer port Data bit 4.
Parallel printer port Data bit 3.
Peripheral/Printer Select (open-drain).
Selects the peripheral/printer when it is set low.
Parallel printer port Data bit 2.
Initialize the peripheral/printer (open drain).
When set low, the peripheral/printer starts its initialization routine.
Parallel printer port Data bit 1.
Peripheral/Printer data error (internal pull-up).
This pin is set low by the peripheral/printer during an error condition.
Parallel printer port Data bit 0.
Peripheral/Printer Auto Feed (open-drain).
Continuous autofed paper is selected when this pin is set low.
Peripheral/Printer data Strobe (open drain).
Data is latched into the peripheral/printer when the nSTROBE is low.
Clear-To-Send signal.
When low, this indicates that the modem or data set is ready to
exchange data. nCTS has no effect on the transmitter.
Data-Terminal-Ready signal.
It is set high (inactive) after a hardware reset or during internal loop-
back mode. When low, this output indicates to the modem or data
set that the UART is ready to establish a communication link. nDTR
has no effect on the transmitter or receiver.
Ring-In detect signal.
+3.3V Voltage Regulator output.
Power and Signal Ground.
Device Supply Inputs.
All should be connected to the VOUT pin.
VOUT voltage is gated by RESET.
Main Power Input.
Connect to USB VBUS or local VDD.
USB 1.1 to Single UART and Printer Port
