20.5.7
The BAAR register defines the address space for memory-referencing BDM commands. Bits [7:5] are
loaded directly from the BDM command, while the low-order 5 bits can be programmed from the external
development system. To maintain compatibility with the Rev. A implementation, this register is loaded any
time the AATR is written. The BAR is initialized to a value of $5, setting “supervisor data” as the default
address space.
20.5.8
The debug module supports concurrent operation of both the processor and most BDM commands. BDM
commands may be executed while the processor is running, except for the operations that access
processor/memory registers as follows:

If set, the Ignore Pending Interrupts bit forces the processor core to ignore any pending interrupt requests
signalled while executing in single-instruction-step mode.
If set, the Single-Step Mode bit forces the processor core to operate in a single-instruction-step mode. While
in this mode, the processor executes a single instruction and then halts. While halted, any of the BDM
commands may be executed. On receipt of the GO command, the processor executes the next instruction and
then halts again. This process continues until the single-instruction-step mode is disabled.
