1.7.4 ACPI Features
Advanced Configuration and Power Interface (ACPI) defines a flexible and abstract
hardware interface that provides a standard method of integrating power manage-
ment features throughout the system. This includes the hardware, the operating sys-
tem, and the application software. As a result, the system can automatically turn
peripherals (CD-ROMs, NICs, storage drives, and printers, for example) on or off.
This includes any consumer devices that may be connected to the system (VCRs,
TVs, telephones, and stereo systems, for example).
In addition to providing operating-system power management, ACPI offers a generic
system event mechanism for Plug and Play and an operating system-independent
interface for configuration control. Plug-and-Play BIOS data structures are lever-
aged, while the implementation is processor architecture-independent and compati-
ble with both Windows 7, Windows Vista, and Windows 2008 Operating Systems.
1.7.5 Slow Blinking LED for Suspend-State Indicator
When the CPU enters a suspend state, the
Power
LED will start blinking to indicate
that the CPU is in suspend mode. Pressing any key on the keyboard will awaken the
CPU, at which time the power LED will stop blinking and remain on.
1.7.6 Super I/O
The Super I/O supports two high-speed,16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as
well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which sup-
port higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management to
reduce power consumption.
1.7.7 Overview of the Renesas SH7757
The X9DRW motherboard family uses the Renesas SH7757 baseboard management
controller (BMC).
