Technical Specifications
nACK/PtrClk/PeriphClk
Busy/PtrBusy/PeriphClk
All modes:
DATA 8 is the MSB, DATA 1 is the LSB.
Compatibility mode:
Acknowledgment low pulse in order to
indicate that data was transferred from
the host.
Negotiation phase:
Low signal indicates IEEE 1284 is
supported; set to high to indicate that the
Xflag and “data available” flag are valid.
Reverse data
transfer phase:
In nibble mode, a low signal indicates that
the nibble data is valid.
Reverse idle phase:
When switched from low to high,
generates an interrupt that notifies the
host that there is data available.
ECP mode:
Used to transfer data from the printer to
the host with handshaking via HostAck
(nAutoFd).
Compatibility mode:
High signal indicates that the printer is not
ready to receive data.
Negotiation phase:
Reflects the BUSY status of the forward
channel.
Reverse data
transfer phase:
In nibble mode, this signal serves as nibble
data bit 3 and then 7.
Reverse idle phase:
Reflects the BUSY status of the forward
channel.
ECP mode:
Used for forward direction flow control.
In reverse direction, this signal is used as
