PRCM Functional Description

3.5.3 PRCM Clock Manager Functional Description

This section describes all modules and features in the high-tier device. To save power, ensure that power
domains of unavailable features and modules are switched off and clocks are cut off.

NOTE:

For more information about clock distribution and control, see the device clock tree tool.

3.5.3.1

Overview

The PRCM module provides control for clock generation, division, distribution, synchronization, and gating.
It distributes the clock sources to all modules in the device.

The device-level clock generation is handled by an internal oscillator (the system clock oscillator) and
DPLLs; clock division and gating are handled by the PRM and the CM sections of the PRCM module.

Figure 3-35

shows the high-level clock-management scheme in the device.
