Not reset. nRESET is the global reset input for the
KS32C65100. For a system reset, nRESET must be held to
low level for at least 65 machine cycles.
Not select information. This input signal is used by parallel
port interface to request 'on-line' status information.
Not strobe. The nSTROBE input indicates when valid data is
on parallel port data bus, PPD[7:0]
Not auto feed. The nAUTOFD input indicates whether data
on the parallel port data bus, PPD[7:0], is an auto feed
command. Otherwise, the bus signals are interpreted as data
only.
Not initialization. The nINIT input signal initializes the parallel
port's input control.
Not parallel port acknowledge. The nACK output signal is
issued whenever a transfer on the parallel port data bus is
completed.
Parallel port busy. The BUSY output signal indicates that the
KS32C65100 parallel port is currently busy.
Parallel port select. The SELECT output signal indicates
whether the device connected to the KS32C65100 parallel
port is 'on-line' or 'off-line'.
Parallel port paper error. PERROR output indicates that a
problem exists with the paper in the ink-jet printer. It could
indicate that the printer has a paper jam or that the printer
is out of paper.
Not fault. The nFAULT output indicates that an error
condition exists with the printer. This signal can be used to
indicate that the printer is out of ink or to inform the user
that the printer is not turned on.
arallel port data bus. This 8-bit, tri-state bus is used to
exchange data between the KS32C65100 and an external
host(peripheral).
