AMD SC1201 SWC Registers, Banks 0 and 1 Common Control and Status Register Map, Type Name Value

SuperI/O Module 32579B

5.6.2SWC Registers

The SWC registers are organized in two banks. The offsets are related to a base address that is determined by the SWC Base Address Register in the logical device configu- ration. The lower three registers are common to the two banks while the upper registers (03h-0Fh) are divided as follows:

•Bank 0 holds reserved registers.

•Bank 1 holds the CEIR Control Registers.

The active bank is selected through the Configuration Bank Select field (bits [1:0]) in the Wakeup Configuration Regis- ter (WKCFG). See Table 5-29 on page 118.

The tables that follow provide register maps and bit defini- tions for Banks 0 and 1.
