CB650M-BX Mother Board
1 - 4
●
Pipelined memory read and write operations that hide memory access
l a t e n c y
●
Demultiplexing of address and data on the bus for nearly 100% bus eff i c i e n c y
4. USB
The CB650M-BX motherboard has two USB ports;one USB peripheral can be
connected to each port. The two USB ports are implemented with stacked
back panel I/O connectors. The CB650M-BX motherboard fully supports
UHCI and uses UHCI-compatible software drivers.
The +5V lines to these ports are protected with a PolySwitch circuit that, like a
self-healing fuse, reestablishes the connection after an overc u r rent condition is
re m o v e d .
●
Self-identifying peripherals that can be plugged in while the computer is
ru n n i n g
●
Automatic mapping function to driver and configuration
●
Support for up to 127 physical devices
5. IDE Support
The CB650M-BX motherboard has two independent bus-mastering IDE
interfaces. These interface support:
●
ATAPI devices(such as CD-ROM devices)
●
ATA devices using these transfer modes
PIO Mode 3
PIO Mode 4
Ultra DMA/33 synchronous-DMA mode
Computer systems that have an unshielded cable attached to a USB
port may not meet FCC Class B requirements, even if no device or a
low-speed USB device is attached to the cable. Use shielded cable that
meets the requirements for full-speed devices.
