2.8 SPI flash (Serial Peripheral Interface)
As SPI Flash
(
Serial Peripheral Interface) offers many benefits including: reduced controller pin
count, smaller and simpler PCBs, reduced switching noise, less power consumption, and lower
system cost
Many of users may consider using a formatted SPI flash to boot for the system or emulate SPI
flash as Floppy (A: Driver or B: Driver). Then you must know how to set for this condition in
CMOS Setup and boot up under DOS 6.22, X-DOS, DR-DOS and Free DOS.

2.9 PWM (Pulse-width modulation)
Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty
cycle, to either convey information over a communications channel or control the amount of
power sent to a load.
The popular applications of pulse width modulation are in speed control of electric motors,
volume control of Class D audio amplifiers or brightness control of light sources and many other
power electronics applications.
The Vortex86DX2 SoC integrated 16 channels of PWM interface enabling the Automation,
robotic industry to a New Age x86 SoC platform and we also offer the sample code of PWM
which will guide the engineer to control the PWM functionality smoothly.
