12.4.15. Watchpoint Value Registers

The WVRs are registers 96-111, at offsets 0x180-0x1BC. Each WVR is associated with a Watchpoint Control Register (WCR), for example:

This pattern continues up to WVR15 with WCR15.

A pair of watchpoint registers, WVRn and WCRn, is called a Watchpoint Register Pair (WRPn).

The watchpoint value contained in the WVR always corresponds to a Data Virtual Address (DVA) and can be set either on:

For a DVA and context ID pair, a WRP and a BRP with context ID comparison capability must be linked. A debug event is generated when both the DVA and the context ID pair match simultaneously. Table 12.25 shows how the bit values correspond with the Watchpoint Value Registers functions.
