1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec-
tion, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports four 360 KB, 720 KB, 1.2 MB, 1.44 MB or
2.88 MB disk drives and data transfer rates of 250 Kbps, 500 Kbps or 1
Mbps.
It also provides two high-speed, 16550 compatible serial communication
ports (UARTs), one of which supports serial infrared communication. Each
UART includes a 16-byte send/receive FIFO, a programmable baud rate
generator, complete modem control capability and a processor interrupt sys-
tem. Both UARTs provide legacy speed with baud rates of up to 115.2
Kbps as well as advanced speeds with baud rates of 250 Kbps, 500 Kbps
or 1 Mbps to support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port
(ECP).
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates.
The SUPER P3TSSA/P3TSSR/P3TSSE accommodates ATX power supplies.
Although most power supplies generally meet the specifications required by
the CPU, some are inadequate.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. Additionally, in ar-
eas where noisy power transmission is present, you may choose to install
a line filter to shield the computer from noise. It is recommended that you
also install a power surge protector to help avoid problems caused by
power surges.
