5.2 Exception Processing Registers

WatchLo (18) and WatchHi (19) Registers

R4000 processors provide a debugging feature to detect references to a selected physical address; load and store operations to the location specified by the WatchLo and WatchHi registers cause a Watch exception (described later in this chapter).

Figure 5-9 shows the format of the WatchLo and WatchHi registers;
Table 5-7 describes the WatchLo and WatchHi register fields.
