18.4.1 Register Descriptions

This section describes the global utilities registers in detail.

18.4.1.1 POR PLL Status Register (PORPLLSR)

PORPLLSR, shown in Figure 18-1, contains the settings for the PLL ratios as set by the

cfg_sys_pll[0:3] and cfg_core_pll[0:1] POR configuration pins. See Section 4.4.3.1, “System PLL

Ratio,” and Section 4.4.3.2, “e500 Core PLL Ratio,” for more information.
