TAGHI signal shares a pin with the BKGD signal. Tagging information is
latched on the falling edge of ECLK.

operate independently - the state of one pin does not affect the function
of the other. The presence of logic level zero on either pin at the fall of
ECLK performs the indicated function. Tagging is allowed in all modes.
Tagging is disabled when BDM becomes active and BDM serial
commands are not processed while tagging is active.
The tag follows program information as it advances through the queue.
When a tagged instruction reaches the head of the queue, the CPU
enters active background debugging mode rather than execute the
instruction.
