1.2 Special Features of the System Board

Watchdog Timer
The Watchdog Timer function allows your application to regularly
"clear" the system at the set time interval. If the system hangs or
fails to function, it will reset at the set time interval so that your
system will continue to operate.
DDR
Double Data Rate SDRAM (DDR SDRAM) is a type of SDRAM
that doubles the data rate through reading and writing at both the
rising and falling edge of each clock. This effectively doubles the
speed of operation therefore doubling the speed of data transfer.
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital
audio signals to a device without having to be converted first to an
analog format. This prevents the quality of the audio signal from
degrading whenever it is converted to analog. S/PDIF is usually
found on digital audio equipment such as a DAT machine or audio
processing device. The S/PDIF connector on the system board sends
surround sound and 3D audio signal outputs to amplifiers and
speakers and to digital recording devices like CD recorders.
Serial ATA Interface with RAID
Serial ATA is a storage interface that is compliant with SATA 1.0
specification. With speed of up to 1.5Gbps, it improves hard drive
performance faster than the standard parallel ATA whose data
transfer rate is 100MB/s. The system board allows configuring RAID
on Serial ATA drives. It supports RAID 0 and RAID 1.
