12. Power Manager (PM)

Rev: 4.1.1.4

Features

Generates clocks and resets for digital logic

On-the-fly frequency change of CPU, HSB and PBx clocks

Sleep modes allow simple disabling of logic clocks and clock sources

Module-level clock gating through maskable peripheral clocks

Wake-up from internal or external interrupts

Automatic identification of reset sources

Supports advanced Shutdown sleep mode

Overview

The Power Manager (PM) provides synchronous clocks used to clock the main digital logic in the

device, namely the CPU, and the modules and peripherals connected to the High Speed Bus

(HSB) and the Peripheral Buses (PBx).

The PM contains advanced power-saving features, allowing the user to optimize the power con-

sumption for an application. The synchronous clocks are divided into a number of clock

domains, one for the CPU and HSB, and one for each PBx. The clocks can run at different

speeds, allowing the user to save power by running peripherals relatively slow, whilst maintain-

ing high CPU performance. The clocks can be independently changed on-the-fly, without halting

any peripherals. The user may adjust CPU and memory speeds according to the dynamic appli-

cation load, without disturbing or re-configuring active peripherals.

Each module has a separate clock, enabling the user to save power by switching off clocks to

inactive modules. Clocks and oscillators can be automatically switched off during idle periods by

the CPU sleep instruction. The system will return to normal operation when interrupts occur.

To achieve minimal power usage, a special sleep mode, called Shutdown is available, where

power on all internal logic (CPU, peripherals) and most of the I/O lines is removed, reducing cur-

rent leakage. Only a small amount of logic, including the 32KHz crystal oscillator (OSC32K) and

the AST remain powered.

The Power Manager also contains a Reset Controller, which collects all possible reset sources,

generates hard and soft resets, and allows the reset source to be identified by software.
