EXTEST Output Bus Tri-State
IEEE Standard 1149.1 mandates that the TAP controller be able
to put the output bus into a tri-state mode.
The boundary scan register has a special bit located at bit #85
(for 119-BGA package) or bit #89 (for 165-FBGA package).
When this scan cell, called the “extest output bus tri-state,” is
latched into the preload register during the “Update-DR” state in
the TAP controller, it directly controls the state of the output
(Q-bus) pins, when the EXTEST is entered as the current
instruction. When HIGH, it enables the output buffers to drive the
output bus. When LOW, this bit places the output bus into a
high Z condition.

This bit can be set by entering the SAMPLE/PRELOAD or
EXTEST command, and then shifting the desired bit into that cell,
during the “Shift-DR” state. During “Update-DR,” the value
loaded into that shift-register cell latches into the preload
register. When the EXTEST instruction is entered, this bit directly
controls the output Q-bus pins. Note that this bit is preset HIGH
to enable the output when the device is powered-up, and also
when the TAP controller is in the “Test-Logic-Reset” state.
