Initial BCLK Frequency [Auto]
This item allows you to set the initial BCLK (base clock) frequency to start overclocking
from the assigned BCLK frequency.
Conguration options: [Auto] [40.0 MHz] – [500.0 MHz]
BCLK Amplitude [Auto]
This item allows you to set the magnitude of the base clock driven for the processor.
Conguration options: [Auto] [700mV] [800mV] [900mV] [1000mV]
BCLK Slew Rate [Auto]
This item allows you to set the speed at which each clock rises and falls.
Conguration options: [Auto] [1.5V/ns] [2.5V/ns] [3.5V/ns] [4.5V/ns]
BCLK Spread Spectrum [Auto]
This item allows you to reduce the EMI. Disable to get more accurate base clocks.
Conguration options: [Auto] [Disabled] [-0.22] [-0.34] [-0.46] [+0.12] [+0.22] [+0.28]
[+0.38] [+0.17]
BCLK Frequency Slew Rate
This item allows you to set frequency update rate. Lower values speed up clock
changes.
