open-collector), the drivers are dynamically
changed from open-collector to totem-pole. The
timing for the dynamic driver change is specified
in the IEEE 1284 Extended Capabilities Port
Protocol
and
ISA
Interface
Standard, Rev. 1.09, Jan. 7, 1993, available
from Microsoft. The dynamic driver change
must be implemented properly to prevent
glitching the outputs.

applies if another data transfer is pending. If no other data transfer is pending, the data
is held indefinitely.
