B.15.4 Forcing DBGACK
Figure B-11 on page B-55 shows that the value of DBGACKI from the core is ORed
with the value held in bit [0] of the debug control register to generate the external value
of DBGACK seen at the periphery of the ARM7TDMI core. This enables the debug
system to signal to the rest of the system that the core is still being debugged even when
system-speed accesses are being performed (when the internal DBGACK signal from
the core is LOW).
