-However more importantly is their ability to do SMartDebug with active probes and probe insertion. This allows you to debug the fabric in real time, without stopping the processor.
+However more importantly is their ability to do SmartDebug with active probes and probe insertion. This allows you to debug the fabric in real time, without stopping the processor.
 
 The probe insertion also allows you to connect pins to a certain input pin. In this case we setup the switches to connect directly to 2 of the LEDs. 
 
 I found it most interesting that even when the board lost power these probe insertions remained.

+They provided a fully connected schematic for the memory writing operations. When pressing button 2 the memory was written with memory, when resetting the controller the memory was returned to default state.
