23.6.12 Breakpoint Address Register (BAR)
23.6.13 Development Port Data Register (DPDR)
This 32-bit special purpose register physically resides in the development port logic. It is used for data
interchange between the core and the development system. An access to this register is initiated using
mtspr and mfspr (SPR 630) and implemented using a special bus cycle on the internal bus.
