12.4.13. Watchpoint Value Registers

Each DBGWVR is associated with a Watchpoint Control Register (DBGWCR). DBGWCRy is the corresponding register for DBGWVRy.

A pair of watchpoint registers, DBGWVRy and DBGWCRy, is called a Watchpoint Register Pair (WRP). DBGWVR0-7 are paired with DBGWCR0-7 to make WRP0-7.

The watchpoint value contained in the DBGWVR always corresponds to a data address and can be set either on:

For a data address and context ID pair, a WRP and the BRP with context ID comparison capability must be linked. A debug event is generated when both the data address and the context ID pair match simultaneously.

Table 12.18 shows the bit assignments.
