Clock Generation Module (MC_CGM)
7.1 Overview
The clock generation module (MC_CGM) generates reference clocks for all 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). A set of MC_CGM registers controls the clock
dividers which are utilized 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 7-1 depicts the MC_CGM block diagram.
