General question: how does ARM core updates its registers?

trace down where all the registers (such as pll setting, IO, ...) get updated. For example, for the STM32F0 processor, below are the code to set system clock but the codes only have the registers that get modified, but how the register get updated by the processor? My guess is there is some type of interrupt

and compiler these specifically for the hardware. Here's a link to CMSIS: file:///C:/LinuxEmbSrc/STM32F0-Discovery_FW_V1.0.0/Libraries/CMSIS/Documentation/CMSIS_Core.htm
