21.8.1 Quick Start Guide for SYSTEM CLOCK - Basic

In this case we apply the following configuration:
  • RC8MHz (internal 8MHz RC oscillator)

    • Divide by four, giving a frequency of 2MHz

  • DFLL (Digital frequency locked loop)

    • Open loop mode

    • 48MHz frequency

  • CPU clock

    • Use two wait states when reading from flash memory

    • Use the DFLL, configured to 48MHz
