2. Write the RSCLKCFG register's PSYSDIV value and MEMTIMU bit if the MEMTIM0 register is
updated in the first step. The new SYSDIV is now in effect.
5.4 Register Map
Table 5-11 on page 258 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: Spaces in the System Control register space that are not used are reserved for future or
internal use. Software should not modify any reserved memory address.
Additional Flash and ROM registers defined in the System Control register space are
described in the “Internal Memory” on page 630.
