SuperI/O Control and Configuration Registers
The SuperI/O configuration registers at indexes 20
ment and the selection of pin multiplexing options. For details, see Section 6.1.8 on page 306.
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 242 and Chapter 6 on page 297.
Control
The only implemented control register for each logical device is the Activate register at index 30
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).
