GENERAL PURPOSE PARALLEL
PRINTER PORT WITH 83 BYTE FIFO
DESCRIPTION
The ST78C34 is a monolithic Bidirectional Parallel
port designed to operate as a general purpose I/O port.
It contains all the necessary input/output signals to be
configured as a CENTRONICS printer port.
The ST78C34 is a general purpose input/output con-
troller with 83 byte internal FIFO. FIFO operation can
be enabled or disabled. For CENTRONICS printer
operation, all registers are mapped to IBM printer port
registers.
The ST78C34 is designed to operate as normal
printer interface without any additional settings. Con-
tents of the FIFO will be cleared after reset or setting
the INIT pin to a low state. The auto FIFO operation
starts after the first -ACK is received from the printer.
Contents of the FIFO transfer to the printer at the
printer loading speed.
