How can I disable ARM RAM/ROM in PSC0?

Hi Champs,

I'm trying to disable the OMAP-L138 ARM RAM/ROM module(LPSC #7) in PSC0, its default state is enable.
But I can not make it disable by following a state transition procedure described in TRM SPRUH77A page-187.
I've done it on DSP side, though.

So, could you please let me know how I can disable the module?

Thanks in advance for your cooperation.

Best regards,
