This is used for configuring the New3DS ARM11 CPU clock-rate. This register is New3DS-only: reading from here on Old3DS always returns all-zeros even when one tried writing data here prior to the read.

On firmlaunch, the kernel sets the mode to O3DS.
    
[[SVC#KernelSetState|svcKernelSetState]] type10, only implemented on New3DS, uses this register. That code writes the following values to this register, depending on the input Param0 bit0 state, and the state of [[CONFIG11 Registers#CFG11_SOCINFO|CFG11_SOCINFO]]:
