This is a system control register block, acting as a bridge to the
|
||
|
|
platform's configuration bus via "system control" interface, addressing
|
||
|
|
devices with site number, position in the board stack, config controller,
|
||
|
|
function and device numbers - see motherboard's TRM for more details.
