2.5.2.1 System Clock Control Register
SCCR is memory-mapped into the SIU register map of the MSC8101.
2.5.2.2 System Clock Mode Register
SCMR is a read-only register that is updated during power-on reset (PORESET) and provides the mode control
signals to the PLLs, DLL, and clock logic. This register reflects the currently defined configuration settings. For
details of the available setting options, see AN2306/D.
