The Processor Dependent Hardware (PDH) controller provides the following features.
• 16-bit PDH bus with reserved address space for the following:
— Flash memory
— Nonvolatile memory
— Scratch RAM
— Real time clock
— UARTs
— External registers
— Firmware read/writable registers
— Two general purpose 32-bit registers
— Semaphore registers

Field Programmable Gate Array
The Field Programmable Gate array (FPGA) provides ACPI and LPC support for the PDH bus and provides
these features:
• ACPI 2.0 interface.
• LPC bus interface to support BMC.
• Decoding logic for PDH devices.
BMC
The BMC supports the industry-standard Intelligent Platform Management Interface (IPMI) specification.
This specification describes the management features that have been built into the system board. These
features include: diagnostics (both local and remote), console support, configuration management, hardware
management and troubleshooting.
The BMC provides the following:
• Compliance with IPMI 1.0.
• Tachometer inputs for fan speed monitoring.
• Pulse width modulator outputs for fan speed control.
• Push-button inputs for front panel buttons and switches.
• One serial port, multiplexed with the system console port.
• Remote access and intelligent chassis management bus (ICMB) support.
• Three I
