Hi community .
Our customer has below question.
The described POR_B and 24MHz to P.95 of "IMX6DQ6SDLHDG rev.1".
"During initial power on while asserting the POR_B reset signal, ensure that 24 MHz clock is active before releasing POR_B."
There are before the cancellation of the POR_B ensures 24 MHz clock is active .
RTC clock (32.768 kHz) have to POR_B unlock provided spec ?
Or, if the timing provisions of 24MHz and POR_B release are protected, do not be a problem even for the RTC.
Solved! Go to Solution.
Hi Takashi
32.768 kHz crystal does not matter as 32 kHz clock will automatically switch
to the internal ring oscillator. 24MHz is necessary for normal operation
of PLLs and arm core.
