Note:
  1. Conditions:
    • No peripheral modules are operating (i.e. all peripherals inactive)
    • All clock generation sources disabled unless otherwise specified. (i.e. XOSC32K=Off)
    • GCLK clock generators 1 to 8 stopped (GENCTRL[8:1].GENEN=0)
    • AHB/APB clocks not needed are masked: AHBMASK=0x70, APB(A/B/C/D)MASK=0x0
    • MCU and AHB clocks undivided
    • I/Os are inactive input mode with input trigger disabled
    • WDT, RTC, CFD Clock Fail Detect disabled
    • RESET = VDDIO
    • NVMCTRL cache enabled
    • BODVDD disabled
    • Note: µA/MHz varies over temperature. Worst case is given by max.
