KV5x HSADC Clock

Hi,

Is it possible to have 80MHZ for the HSADC clock when the CPU clock is 220MHZ and the Fast peripheral clock is 110MHZ? If not, what is the maximum HSADC clock in this situation?

And when CPU clock is 200MHZ and Fast peripheral clock is 100MHZ, what is the maximum HSADC clock in this situation?

Ari.

Page 982 of the Reference Manual shows that the HSADC clock = CPU_CLK/(HSADCx_CTROL2.DIVA +1), with the maximum in 80MHZ.

So, for CPU CLOCK = 220MHZ  => HSADC CLOCK = 220/3 = 73.33MHZ.
