The two-wire debug interface allows programming of the on-chip flash, and it provides access to memory
and register contents and debug features such as breakpoints, single-stepping, and register modification.
The debug interface uses I/O pins P2.1 and P2.2 as debug data and debug clock, respectively, during
debug mode. These I/O pins can be used as general-purpose I/O only while the device is not in debug
mode. Thus, the debug interface does not interfere with any peripheral I/O pins.
