My customer plans to use 32K crystal for i.MX25 OSC32K_EXTAL.
On their board, the 32K clock input from the crystal can be stable at 500mS later after the release of POR.
Is it OK?
Actually, the 32K clock should be stable before POR releases, because after POR , ROM code will use the clock to do booting configurations.
But according to the customer's issue, if system is not stable, she can consider delaying the time of POR over 500ms !
Hope the suggestion can help you !
