The Watchpoint Value Registers (WVRs)
are registers 96-99, at offsets
Each WVR is associated with a Watchpoint Control Register (WCR),
WVR0 with WCR0
WVR1 with WCR1.
This pattern continues up to WVR3 with WCR3.
Table 10.6 shows the WVRs and corresponding WCRs.
|Watchpoint Value Registers||Watchpoint Control Registers|
|Register number||Offset||Name||Register number||Offset||Name|
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:
a DVA and context ID pair.
For a DVA and context ID pair, a WRP and a BRPs 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 10.7 shows how the bit values correspond with the Watchpoint Value Registers functions.
