CPU Core Register Descriptions
5.5.2.106 Bus Controller Extended Debug Registers 6 and 7 MSR (BXDR6_BXDR7_MSR)
MSR Address
Type
Reset Value
BXDR6 (bits [31:0]) contains the status of the extended bus controller breakpoints. When a breakpoint occurs, the corre-
sponding status bit is set in this register. The status bits remain set until cleared by an MSR write.
BXDR7 (bits [63:32]) is used to enable and specify the type of BXDR0-BXDR3. BXDR7 is also used to specify the length of
the breakpoint. For example, if BXDR0 is set to 00000006h, and BXDR7 indicates it has a length of 2 bytes, then an access
to 00000006h or 00000007h triggers the breakpoint. BXDR0 and BXDR1 can be paired to specify a range breakpoint if the
LEN0 or LEN1 field of BXDR7 is set accordingly. BXDR2 and BXDR3 can be paired to specify a range breakpoint if the
LEN2 or LEN3 field of BXDR7 is set accordingly.
