Hi,
Our customer is trying to boot AM3874 from external asic. Customer uses BTMODE[10]=0(XIP(NOR) boot mode).
At the above condition, I have some questions. Please see the following.
1. Customer would like to chagnge the clock when GPMC is working. How long is the lock time of PLL to output new clock from GPMC_CLK when the frequency is changed?
2. Are there any way to recognize that PLL lock is completed?
Please adivse me the above.
Best regards,
Michi
