7.8.3.8 PLL1 PLLDIV Ratio Change Status Register (DCHANGE)
Whenever a different ratio is written to the PLLDIV10 register, the PLLCTRL flags the change in the
PLLDIV ratio change status register (DCHANGE). During the GO operation, the PLL controller will only
change the divide ratio of the SYSCLK with the bit set in DCHANGE. Note that changed clocks will be
automatically aligned to other clocks if the corresponding ALN bit is set. The PLLDIV divider ratio change
status register is shown in Figure 7-21 and described in Table 7-27.
