a error condition at the printer. Bit 3 of the printer status
register reads the ERR# input. Refer to
Parallel port description for use of this pin in ECP and
EPP mode. This high current output selects the floppy
Disk side for reading or writing. A logic “1” on this pin
means side 0 will be accessed while a logic “0” means
side 1 will be accessed.
This output is bit 2 of the printer control register. This is
used to initiate the printer when low. Refer to parallel
port description for use of this pin in ECP and EPP
mode. This high current low active output determines
the direction of the head movement. A logic “1” on this
pin means outward motion, while a logic “0” means
inward motion.
This active low output selects the printer. This is the
complement of bit 3 of the printer control register. Refer
to parallel port description for use of this pin in
ECP and EPP mode. This active low high current driver
issues a low pulse for each track to track movement of
the head.
