B.11. Coupling breakpoints and watchpoints

You can couple watchpoint units 1 and 0 together using the CHAIN and RANGE inputs. The use of CHAIN enables Watchpoint 0 to be triggered only if Watchpoint 1 has previously matched. The use of RANGE enables simple range checking to be performed by combining the outputs of both watchpoints.
