Part Number:DM385
Hello Everyone,
I'm trying to enable the AUXOSC clock source for the McASP. My DEVOSC is 20MHz and I can't generate the correct clocks for my audio codec with it, so I'd like to configure the system to allow AUXOSC to be used by the McASP. AUXOSC is being driven by a 22.579 MHz clock on my system.
According to Figure 2-11 (Audio Clock Structure) in the TRM, there's a mux I can change to switch between using the DEVOSC and the AUXOSC. I believe this mux is controlled by OSC_SRC register bit 24 called AUDIO_PLL_SOURCE. I've tried searching for where this is getting initialized but I'm not having much luck. Could anyone give me any guidance on how to change the clock over? Also, what further changes will I need to make to get this working?
Thanks!
