Memory Access at Address A and Value on Data

Bus Mismatch

This mode is used to trigger on a program instruction read and/or write of a NOT matching

byte value at Address A memory location.

When choosing this trigger type, the trigger B address is used as a mismatch value rather

than an address. Also when setting this trigger via a context sensitive context menu, the

following message is displayed if the match value was never set.
