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 controller 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. Contents 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.
FEATURES
• 83 bytes of printer output FIFO
• Bi-directional software parallel port
• Bi-directional I/O ports
• Register compatible to IBM XT, AT, compatible 386, 486
• Selectable interrupt polarity
• Selectable FIFO interrupts
