19.8.2 Burst Mode
Burst mode provides the highest scan throughput of all modes. CPU operation is stalled on the
      instruction following the instruction that sets SGO and remains stalled
      until the last NVM location has been transferred. Once hardware clears SGO, the CPU resumes
      normal operation.
Important: In
        Burst mode, software cannot clear SGO while the scan is in progress since the CPU cannot
        execute instructions while stalled.
