7.7.3.4 PLL Controller Divider 4 Register

The PLL controller divider 4 register (PLLDIV4) is shown in Figure 7-14and described in Table 7-22.

Besides being used as the EMIFA internal clock, SYSCLK4 is also used in other parts of the system. Disabling this clock will cause unpredictable system behavior. Therefore, the PLLDIV4 register should never be used to disable SYSCLK4.
