the TAP controller, it will directly control the state of the output
(Q-bus) pins, when the EXTEST is entered as the current
instruction. When HIGH, it will enable the output buffers to drive
the output bus. When LOW, this bit will place 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 will latch into the preload

register. When the EXTEST instruction is entered, this bit will
directly control 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.
