Memory map and register definition

13.2 Memory map and register definition
The SIM module contains many fields for selecting the clock source and dividers for
various module clocks. See the
including block diagrams and clock definitions.
The SIM registers can be written only in supervisor mode. In
user mode, write accesses are blocked and will result in a bus
error.
The SIM_SOPT1 register is located at a different base address
than the other SIM registers.
