Register Map
Table 6-1 on page 63 lists the System Control registers, grouped by function. The offset listed is a
hexadecimal increment to the register’s address, relative to the System Control base address of
0x400F.E000.
Note:
Select the desired system divider (SYSDIV) in RCC/RCC2 and set the USESYS bit in RCC. The
SYSDIV field determines the system frequency for the microcontroller.
Wait for the PLL to lock by polling the PLLLRIS bit in the Raw Interrupt Status (RIS) register.
Enable use of the PLL by clearing the BYPASS bit in RCC/RCC2.
Spaces in the System Control register space that are not used are reserved for future or
internal use by Luminary Micro, Inc. Software should not modify any reserved memory
address.
