- Define CPU PLL multiplier. PLL is calculated by formula:
- PLL Frequency = (PLL Multiplier / 2) * 3686400 Hz
- Default value is 40, for achieve 73 MHz.
+ Raise CPU frequency to 90 MHz. This operation can be performed
+ only for devices which allow to operate at 90 MHz.
+ If option is not selected, CPU frequency will set to default 73 MHz.
