Development Capabilities and Interface
20.3.2 Basic Operation
20.3.2.1 INSTRUCTION SUPPORT. There are four instruction address comparators (A, B,
C, and D). Each one is 30 bits long and generates two output events—equal to and less
than. These signals generate one of four events—equal to, not equal to, greater than, or less
than. The instruction watchpoints and breakpoint are generated with these events according
to your programming. Using the OR option enables “out of range” detect.
