SuperI/O Control and Configuration Registers
The SuperI/O Configuration registers at indexes 20h and 27h are mainly used for part identification, global power manage-
ment and the selection of pin multiplexing options. For details, see Section 2.8.
Logical Device Control and Configuration Registers
A subset of these registers is implemented for each logical device. See functional block description in the following sections.
