lowest power consumption during sleep in enCoRe II LV devices

Question: How to ensure lowest power consumption during sleep in enCoRe II LV devices?

 

Answer:

    Before the device is put to sleep, the following must be ensured for the lowest power consumed:    

  1.   All GPIO pins must be set to outputs and driven low except P1.0 and P1.1 .
  2.   P1.0 and P1.1 should be configured and inputs with pull-ups enabled.
  3.   Make sure the 32-kHz oscillator clock is not selected as clock source to ITMRCLK, TCAPCLK, and not even as clock output source onto P01_CLKOUT pin.
