DATA and ecpAFifo PORT
ADDRESS OFFSET = 00H
Modes 000 and 001 (Data Port)
The Data Port is located at an offset of '00H' from
the base address. The data register is cleared at
initialization by RESET. During a WRITE
operation, the Data Register latches the contents
of the data bus on the rising edge of the nIOW
input. The contents of this register are buffered
(non inverting) and output onto the PD0 - PD7
ports. During a READ operation, PD0 - PD7 ports
are read and output to the host CPU.
Mode 011 (ECP FIFO - Address/RLE)
A data byte written to this address is placed in the
FIFO and tagged as an ECP Address/RLE. The
hardware at the ECP port transmits this byte to the
peripheral automatically. The operation of this
register is ony defined for the forward direction
(direction is 0). Refer to the ECP Parallel Port
Forward Timing Diagram, located in the Timing
Diagrams section of this data sheet .
DEVICE STATUS REGISTER (dsr)
ADDRESS OFFSET = 01H
The Status Port is located at an offset of '01H'
from the base address. Bits 0 - 2 are not
implemented as register bits, during a read of the
Printer Status Register these bits are a low level.
The bits of the Status Port are defined as follows:
BIT 3 nFault
The level on the nFault input is read by the CPU
as bit 3 of the Device Status Register.
BIT 4 Select
The level on the Select input is read by the CPU
as bit 4 of the Device Status Register.
100
BIT 5 PError
The level on the PError input is read by the CPU
as bit 5 of the Device Status Register. Printer
Status Register.
BIT 6 nAck
The level on the nAck input is read by the CPU as
bit 6 of the Device Status Register.
BIT 7 nBusy
The complement of the level on the BUSY input is
read by the CPU as bit 7 of the Device Status
Register.
DEVICE CONTROL REGISTER (dcr)
ADDRESS OFFSET = 02H
The Control Register is located at an offset of
'02H' from the base address. The Control
Register is initialized to zero by the RESET input,
bits 0 to 5 only being affected; bits 6 and 7 are
hard wired low.
BIT 0 STROBE - STROBE
This bit is inverted and output onto the nSTROBE
output.
BIT 1 AUTOFD - AUTOFEED
This bit is inverted and output onto the nAUTOFD
output. A logic 1 causes the printer to generate a
line feed after each line is printed. A logic 0
means no autofeed.
BIT 2 nINIT - nINITIATE OUTPUT
This bit is output onto the nINIT output without
inversion.
BIT 3 SELECTIN
This bit is inverted and output onto the nSLCTIN
output. A logic 1 on this bit selects the printer; a
logic 0 means the printer is not selected.
BIT 4 ackIntEn - INTERRUPT REQUEST
ENABLE
The interrupt request enable bit when set to a high
level may be used to enable interrupt requests
from the Parallel Port to the CPU due to a low to
high transition on the nACK input. Refer to the
description of the interrupt under Operation,
Interrupts.
