ENABLE
For each of the bits 7:0 in the control value register, there is a corresponding bit in the
control mask register. These bits remove the dependency on particular signals.

In the ARM7TDMI core EmbeddedICE Logic, the RANGEOUT
output of Watchpoint 1 is connected to the RANGE input of
Watchpoint 0. Connection enables the two watchpoints to be
coupled for detecting conditions that occur simultaneously, such
as for range checking.
When a watchpoint match occurs, the internal BREAKPT signal
is asserted only when the ENABLE bit is set. This bit exists only
in the value register. It cannot be masked.
