•

Global clock gating refers to clock gating inside the CRG module which gates entire clock

domains. Figure 5-2 illustrates the global clock gating on the MAC72xx. More information on this

can be found in the CRG documentation.

•

Local clock gating is implemented inside the CGL, and gates a particular clock for a particular

module. Please refer to the individual chapters for information on gating conditions.

A low power STOP mode is not supported on the MAC72xx.

Since STOP mode is not implemented on the MAC72xx, the user may only control the granularity of

power consumption in DOZE mode, or via the MDIS bit in each module.This topic is discussed in more

detail in Section Chapter 3, “Low Power Modes”.

Figure 5-8 shows the overview of the clock gating and distribution on the MAC72xx.
