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 defined only for the forward direction. The bit definitions are as follows:
7 6 5 4 3 2 1 0
Address or RLE
Address/RLE
5.3.3 Device Status Register (DSR)
These bits are at low level during a read of the Printer Status Register. The bits of this status register
are defined as follows:
7 6 5 4 3 2 1 0
nFault
Select
PError
nAck
nBusy
1
1
1
Bit 7: This bit reflects the complement of the Busy input.
Bit 6: This bit reflects the nAck input.
Bit 5: This bit reflects the PError input.
Bit 4: This bit reflects the Select input.
Bit 3: This bit reflects the nFault input.
Bit 2-0: These three bits are not implemented and are always logic one during a read.
