General Description
Ordering Information
The Nm9715 is a dual 1284 parallel port controller with
PCI bus interface. Nm9715 fully supports the existing
Centronics printer interface as well as PS/2, EPP, and
ECP modes.
The Nm9715 is ideally suited for PC applications, such
as high speed parallel port. The Nm9715 is available in
128-Pin QFP package, It is fabricated in an advanced
in submicron CMOS process to achieve low drain power
and high speed requirements.

Description
PCI System reset (avtice low). Resets all internal register, sequencers, and
signals to a consistent state. During reset condition AD31-0, nSER are three-
stated.
Multiplexed PCI address / data bus. A bus transaction consists of an address
phase followed by one or more data phase. During the address phase AD31-
0 contain a physical address. Write data is stable and valid when nIRDY and
nTRDY are asserted (active).
See AD31-29 description.

See AD31-29 description.
Frame is driven by the current master to indicate the beginning and duration
of an access. nFRAME is asserted to indicate a bus transaction is beginning.
While nFRAME is active, data transfer continues.
Initiator Ready. During a write, nIRDY asserted indicates that the initiator is
driving valid data onto the data bus. During a read, nIRDY asserted indicates
that the initiator is ready to accept data from the Nm9715.
Target Ready (three-state). It is asserted when Nm9715 is ready to complete
the current data phase.
Nm9715 asserts nSTOP to indicate that it wishes the initiator to stop the
transaction in process on the current data phase.
Lock indicates an atomic operation that my require multiple transactions to
complete.
Initialization Device Select. It is used as a chip select during configuration
read and writes transactions.
Device Select (three-state). Nm9715 asserts nDEVSEL when the Nm9715
has decoded its address.
Parity Error (three-state). Is used to report parity errors during all PCI trans-
actions except a Special Cycle. The minimum duration of nPERR is one clock
cycle.
