9.7. Coupling Breakpoints and Watchpoints

Watchpoint units 1 and 0 can be coupled together via the CHAIN and RANGE inputs.

CHAIN

enables watchpoint 0 to be triggered only if watchpoint 1 has previously matched.

RANGE

enables simple range checking to be performed by combining the outputs of both watchpoints.
