ADDITIONAL LOCAL IO FUNCTIONS
9-2 PP 41x/03x
Most of the addresses are standard PC-AT compatible values, but at addresses 0210h - 021Fh
and 0CA9h – 0CABh the board provides custom Status and Control registers for the board specific
features.
There are 13 byte wide Status and Control registers. They fall into four groups, namely, general-
purpose registers, temperature sensor data registers, ACPI registers and IPMI SMIC interface
registers. They are accessed at the following addresses:
• 210h for Status & Control Register 0.
• 211h for Status & Control Register 1.
• 212h for Status & Control Register 2.
• 213h for General Purpose I/O Register.
• 214h for CPCI Status Register.
• 215h for Interrupt Control Register.
• 216h for Analog Temperature Sensor Data Register.
• 21Dh for Interrupt Configuration Register.
• 21Eh for ACPI PM1 Control Register low byte.
• 21Fh for ACPI PM1 Control Register high byte.
• 0CA9h for SMIC Data Register.
• 0CAAh for SMIC Control/Status Register.
• 0CABh for SMIC Flags Register.
NOTE: All other I/O addresses in the range 0210h – 021Fh are reserved. Do not write to
any of these addresses.
