45.8 Wake-Up Time

Conditions:

  • VDD = 5.0V
  • CPU clock = OSC48M @8Mhz
  • 0 Wait-state
  • Cache enabled
  • Flash in WAKEUPINSTANT mode (NVMCTRL.CTRLB.SLEEPPRM=1)

CPU sets an IO by writing PORT->IOBUS without jumping in an interrupt handler (Cortex M0+ register PRIMASK=1). The wakeup time is measured between the edge of the wakeup input signal and the edge of the GPIO pin.
