•

Power reset manager (PRM): Handles the power, reset, wake-up management, and system clock

source control (oscillator)

•

Clock manager (CM): Handles the clock generation, distribution, and management.

Table 2-6 lists the physical addresses of the PRM and CM modules. Table 2-7 through Table 2-18 provide

For more details on the PRCM, see Section 7 of this data sheet, Power, Reset, Clocking and Interrupts,

and the PRCM chapter of the AM389x Sitara ARM Processors Technical Reference Manual (literature
