A power control signal controls a low-power mode, a USB connection, and an asynchronous reset function for a bridge circuit. Another power control signal controls both a high power mode and a low power mode for an attached device. The two power control signals reduce the number of pins required on the bridge circuit for controlling its own power related operations and power related operations of the attached device.

Power management system for bridge circuit

ATA devices, such as mass storage units, have increasingly larger storage sizes that use larger configuration register sizes. A command block format allows the USB/ATA bridge circuit to be used with ATA devices with larger registers and at the same time operates with earlier ATA command block formats.
