5.5.2.107 Bus Controller Debug Registers 0 through 3 MSRs
Each of these registers specifies an address that must match the physical address currently in the bus controller in order to
trigger the breakpoint. BDR7 is used to enable and specify the type of BDR0-BDR3. If a breakpoint is configured as a mem-
ory breakpoint, the address is matched on a QWORD granularity. If a breakpoint is configured as an I/O or MSR breakpoint,
the address is matched based on all 32 bits.
