description: |
|
|
Test chips for ARM Versatile Express platform implement SCC (Serial
|
|
Configuration Controller) interface, used to set initial conditions
|
|
for the test chip.
|
|
|
|
In some cases its registers are also mapped in normal address space
|
|
and can be used to obtain runtime information about the chip internals
|
|
(like silicon temperature sensors) and as interface to other subsystems
|
|
like platform configuration control and power management.
