Pervasive

= ARM Clocks = The clocks are controlled by two registers at  (ScePervasiveBaseClk). Currently, it is unknown how the values are interpreted. However,  (one word) takes values 0 to 16, and increases clock speed while   (single byte) takes values 0 to 8 and decreases clock speed. It is likely related to a PLL multiply and divide function.

The following are tests run to determine what the values of each register corresponds to. It appears that the maximum clock speed is 500MHz and the minimum clock speed is 16MHz.
