In figure 8-2 USB Boot Flow of IMX6DQRM Rev. 2, it said ARM core will reset if no any activity within 32 seconds when WDOG_ENABLE=1. However, in ERR006282 of IMX6DQCEC Rev. 4. The workaround #2 said, the Watchdog timer begins a 90-second countdown and, if nothing interrupts this process, the part resets.

1. The 32 and 90 seconds. Which one is right?

2. Is this delay time can change or not?
