CPU is running on Flash with 3 wait states

Note:
  1. Conditions:
    • No peripheral modules are operating (i.e., all peripherals are inactive)
    • MCU is running on Flash with 1 wait states unless otherwise specified
    • The NVMCTRL cache is enabled
    • BOD33 disabled
    • I/Os are inactive input mode with input trigger disabled
    • All clock generation sources disabled unless otherwise specified.
    • GCLK clock generators 1 to 8 stopped (GENCTRL[8:1].GENEN = 0)
    • CPU, AHB clocks undivided:
      • APBA clock divided by 4
      • APBB and APBC bridges off
    • The following AHB module clocks are running: NVMCTRL, APBA bridge
      • All other AHB clocks stopped
    • The following peripheral clocks running: PM, SYSCTRL, RTC
      • All other peripheral clocks stopped
    • RESET# = VDDIO
    • Power consumption varies over temperature. Worst case is given by max.
