Background Debug Mode (BDM) Interface
20.5.6
The CSR defines the debug configuration for the processor and memory subsystem. In addition to defining
the microprocessor configuration, this register also contains status information from the breakpoint logic.
The CSR is cleared during system reset. The CSR can be read and written by the external development
system and written by the supervisor programming model. The CSR is accessible in supervisor mode as
debug control register $0 using the WDEBUG instruction and through the BDM port using the RDMREG
and WDMREG commands.

If set, the Enable Breakpoint Level bit serves as the global enable for the breakpoint trigger. If cleared, all breakpoints
are disabled.
If set, the Enable Data Breakpoint for the Data Longword bit enables the data breakpoint based on the entire
processor’s local data bus. The assertion of any of the ED bits enables the data breakpoint. If all bits are cleared,
the data breakpoint is disabled.
If set, the Enable Data Breakpoint for the Lower Data Word bit enables the data breakpoint based on the low-order
word of the processor’s local data bus.
If set, the Enable Data Breakpoint for the Upper Data Word bit enables the data breakpoint trigger based on the
high-order word of the processor’s local data bus.
If set, the Enable Data Breakpoint for the Lower Lower Data Byte bit enables the data breakpoint trigger based on
the low-order byte of the low-order word of the processor’s local data bus.
If set, the Enable Data Breakpoint for the Lower Middle Data Byte bit enables the data breakpoint trigger based on
the high-order byte of the low-order word of the processor’s local data bus.
If set, the Enable Data Breakpoint for the Upper Middle Data Byte bit enables the data breakpoint trigger on the
low-order byte of the high-order word of the processor’s local data bus.
If set, the Enable Data Breakpoint for the Upper Upper Data Byte bit enables the data breakpoint trigger on the
high-order byte of the high-order word of the processor’s local data bus.
The Data Breakpoint Invert bit provides a mechanism to invert the logical sense of all the data breakpoint
comparators. This can develop a trigger based on the occurrence of a data value not equal to the one programmed
into the DBR.
If set, the Enable Address Breakpoint Inverted bit enables the address breakpoint based outside the range defined
by ABLR and ABHR. The assertion of any of the EA bits enables the address breakpoint. If all three bits are cleared,
this breakpoint is disabled.
If set, the Enable Address Breakpoint Range bit enables the address breakpoint based on the inclusive range
defined by ABLR and ABHR.
If set, the Enable Address Breakpoint Low bit enables the address breakpoint based on the address contained in
the ABLR.
If set, the Enable PC Breakpoint bit enables the PC breakpoint.
If set, the PC Breakpoint Invert bit allows execution outside a given region as defined by PBR and PBMR to enable
a trigger. If cleared, the PC breakpoint is defined within the region defined by PBR and PBMR.
