The data sheet for the TMS320DMS816x indicates that the maximum clock rate of the DSP is 1.0 GHz.
I am verified the DSP clock rates in the TRM by comparing DSP's TSC against a wall clock time of 2 minutes. Using the default settings for MAINPLL_FREQ1 setting of 0x98800000 and a MAINPLL_DIV1 setting of 0x00000102, I'm getting a DSP clock rate of around 800MHz. According to the TRM, I'm supposed to get 813MHz. When I set MAINPLL_FREQ1 to 0x9e000000 and MAINPLL_DIV1 to 0x00000101, I'm getting a DSP clock rate of around 975MHz versus 987MHz in the TRM.
What would happen if I were to set MAINPLL_FREQ1 to 0x9D000000 and MAINPLL_DIV1 to 0x00000101. Would I potentially get a DSP clock rate of 1.06GHz? Would the DSP work correctly at rates above 1.0GHz?
