Debug in Depth
In the case of DBGACK, the value of DBGACK from the core is ORed with the value
held in bit 0 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,
in which case the internal DBGACK signal from the core is LOW.
