F81866A
UART Data Terminal Ready. An active low signal
DTR5#
O12
informs the modem or data set that controller is
ready to communicate.
GPIO64
I/OOD12st, 5v
General Purpose IO.
DSKCHG#
21
INst,5v
3VCC
Diskette change. This signal is active low at power
on and whenever the diskette is removed.
Data Set Ready. An active low signal indicates the
DSR5#
INst,5v
modem or data set is ready to establish a
communication link and transfer data to the UART.

Description
FANIN3
INst,5v
Fan 3 tachometer input.
An active high input on this pin indicates that the
102
SLCT
INst,5v
3VCC printer is selected. Refer to the description of the
parallel port for definition of this pin in ECP and EPP
mode.
GPIO70
I/OOD12st, 5v
General purpose IO.
An active high input on this pin indicates that the
PE
INst,5v
printer has detected the end of the paper. Refer to the
description of the parallel port for the definition of this
pin in ECP and EPP mode.
103
FANCTL3
OOD12,5v
AOUT
3VCC Fan 3 control output. This pin provides PWM
duty-cycle output or a DAC voltage output.
Power on Strapping pin:
PWM _DAC3
INst,5v
1: PWM mode.
0: Default is DAC mode for FANCTL3 (internal pull
down 100k Ω ).
GPIO71
I/OOD12st, 5v
General purpose IO.
An active high input indicates that the printer is not
104
BUSY
INst,5v
3VCC ready to receive data. Refer to the description of the
parallel port for definition of this pin in ECP and EPP
mode.
GPIO72
I/OOD12st, 5v
General purpose IO.
An active low input on this pin indicates that the
105
ACK#
INst,5v
3VCC printer has received data and is ready to accept more
data. Refer to the description of the parallel port for
the definition of this pin in ECP and EPP mode.
GPIO73
I/OOD12st, 5v
General purpose IO.
Output line for detection of printer selection. Refer to
