TPS659113 first configuration

Other Parts Discussed in Thread: AM3874

I have a board similar with TMDXEVM8148. One default voltage of tps659113 is in top boundary of absolute maximum rating (1.5V) for am3874 processor (in TMDXEVM8148 this voltage is CVDD_DSP).
I guess if i run the board then the processor will be ruined before i configure tps659113. Am i right?  How i should configure tps659113 without any processor damage?

    The output voltage of 1.2V is below the maximum operating conditions listed as 1.5V. If you have concerns about operating at this voltage for extended periods of time you can verify with the sitarra forum if they have seen any issues with this design, but if they did have immediate damage I assume it would have been apparent before release.

    If you want to reduce the voltage you can adjust this value over the i2c interface (device address is 0x2D), with the VDD2 OP or SR register depending on how your particular design is configured.
