Errata 156 of nRF52832 Rev. 1

Hi all

I've two questions regarding errata 156:

  1. Am I assuming right that, as long as I don't use WFI or WFE, this errata has not effect?

  2. Are the two consecutive TASK_CLR[n] and TASK_CLR[n+1], as described in the workaround, always setting the system back to the original mode? E.g. I want to use the LOWPOWER mode and trigger TASK_CLR[1] and afterwards TASK_CLR[2], does this restore the original mode (LOWPOWER) or does this switch to the CONSTLAT mode?

Many thanks in advance.

Kind regards

    1. Correct. It changes the sub power mode which is in effect during sleep.

    2. Odd values will set the system in low power mode, so triggering TASK_CLR[1] will set the system in low power. Triggering TASK_CLR[2] will set the system in constant latency mode. So if you have configured the system for low power, and trigger TASK_CLR[1], it should remain in low power mode.
