Standard Configuration Registers

SuperI/O Control and Conﬁguration Registers

The SuperI/O configuration registers at indexes 2016 and 2716 are mainly used for part identification, global power manage-

ment and the selection of pin multiplexing options. For details, see Section 6.1.8 on page 343.

Logical Device Control and Conﬁguration Registers

A subset of these registers is implemented for each logical device. See the functional block descriptions in Chapter 5 on

page 277 and Chapter 6 on page 335.

Control

The only implemented control register for each logical device is the Activate register at index 3016. Bit 0 of Activate register

controls the activation of the associated functional block. Activation enables access to the functional block’s registers and

attaches the functional block’s system resources (e.g., address space and interrupts), which are unused as long as the block

is not activated. Other effects may apply on a function-specific basis (such as clock enable and active pinout signaling).
