System Cpu Mode - Texas Instruments SimpleLink CC2620 Technical Reference Manual

Introduction
Table 6-2 lists the four defined power modes for the power-saving features in TI-RTOS, as shown in
Table 6-1. The power modes are discussed in detail in
Power Mode
Active mode
Idle mode
Standby mode
Shutdown mode

6.1.1 System CPU Mode

The following chapter refers to the system CPU mode so it is important to understand what this means.
The system CPU has three different operation modes: run, mode, and deepsleep (see
mode is used to gate internal clocks in the system CPU, in addition to peripheral clocks that may be gated
in accordance to the current system CPU mode. Deepsleep mode is, in some cases, one of several
requirements for powering down voltage and power domains.

Table 6-2. Power Modes in TI-RTOS
Description
The system CPU is running.
The power domain in which CPU resides is off.
All power domains are powered off and voltage domains are supplied by the micro LDO.
Only I/Os maintain their operation. All voltage regulators, voltage, and power domains are off.

Description
WFI and WFE both inactive, CPU_SCS:SCR.SLEEPDEEP is don't care
WFI or WFE active and CPU_SCS:SCR.SLEEPDEEP = 0
WFI or WFE active and CPU_SCS:SCR.SLEEPDEEP = 1
