The Software reset makes it possible to issue a system reset from software by writing to the
Software Reset bit in the Reset Control Register.The reset will be issued within 1-2 system clock
CPU cycles after writing the bit. It is not possible to execute any instruction from a software reset
is requested and until it is issued.
Figure 8-7.
The Program and Debug Interface reset contains a separate reset source that is used to reset
the device during external programming and debugging. This reset source is only accessible
from debuggers and programmers.
