IORWatch
interface represents a user probe that is fired when a watchpoint detects an access to an IO register where the watch has been inserted. Direct as well as indirect accesses (through pointers) are monitored. Implicit accesses for special registers such as SPL, SPH, and SREG in push, pop, call, sei, etc instructions are NOT MONITORED. These instructions are syntactically apparent in the program and can be probed with Simulator.Probe
instructions. This interface extends the Simulator.Watch
interface with methods to trap reads and writes to individual bits within a register.
