5 Clock Generation Module (MC_CGM)
5.1 Overview
The clock generation module (MC_CGM) generates reference clocks for all the SoC blocks.
The MC_CGM selects one of the system clock sources to supply the system clock. The
MC_ME controls the system clock selection (see the MC_ME chapter for more details).
Peripheral clock selection is controlled by MC_CGM control registers. A set of MC_CGM
registers controls the clock dividers which are used for divided system and peripheral clock
generation. The memory spaces of system and peripheral clock sources which have
addressable memory spaces are accessed through the MC_CGM memory space. The
MC_CGM also selects and generates an output clock.
Figure 26 depicts the MC_CGM Block Diagram.
