Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the power manager driver.
It also gives an example of the usage of the PM on UC3 products. This example shows how to configure the Power Manager(PM) and the System Control Interface(SCIF) (only for devices that include a SCIF module) to use Oscillator 0 as source of main clock and configure a generic clock GCLK with this OSC0 as input. The generic clock 0 can be then viewed on the GCLK pin (this is the oscillator 0 frequency). Once these configurations are done, the example goes into sleep mode while still maintaining GCLK output.

Compilation Info

This software was written for the GNU GCC for AVR32 and IAR Systems compiler for AVR32. Other compilers may or may not work.

Device Info

All AVR32 devices with a PM module or AVR32 devices with a PM module and a SCIF module can be used. This example has been tested with the following setup:

• EVK1100 evaluation kit
• EVK1101 evaluation kit
• EVK1104 evaluation kit
• STK600 starter kit with the RCUC3L0 routing card
• STK600 starter kit with the RCUC3D routing card
• UC3C_EK evaluation kit

Setup Information

CPU speed: OSC0 MHz

On EVK1100, GCLK_0_1 is pin number 51 (PB19) with AT32UC3A0512 in QFP144 package.

• Check GCLK0 pin with an oscilloscope, this is OSC0 frequency (12MHz).

On EVK1101, GCLK_2 is pin number 30 (PA30) with AT32UCB0256 in QFP64 package.

• Check GCLK2 pin with an oscilloscope, this is OSC0 frequency (12MHz).

On EVK1104, GCLK_1_0 is pin number 43 (PB11) with AT32UC3A3256 in QFP144 package.

• Check GCLK1 pin with an oscilloscope, this is OSC0 frequency (12MHz).

On the STK600 + RCUC3L0 setup, insert a 12MHz crystal in the STK600 crystal socket. GCLK_1_0 is GPIO pin 6/pin pa06/pin#10 on a UC3L QFP48 package; for the RCUC3L0 routing card, this pin is mapped on STK600.PORTA.PA6.

• Check the GCLK1 pin with an oscilloscope, it should oscillate at the crystal frequency (12MHz).

On the STK600 + RCUC3D setup, insert a 12MHz crystal in the STK600 crystal socket. GCLK0 is GPIO pin 3/pin pa03/pin#7 on a UC3D QFP64 package; for the RCUC3D routing card, this pin is mapped on STK600.PORTA.PA3.

• Check the GCLK1 pin with an oscilloscope, it should oscillate at the crystal frequency (12MHz).

On UC3C_EK, GCLK_0_2 is pin number 54 (PB22) with AT32UC3C0512C in QFP144 package.

• Check GCLK1 pin with an oscilloscope, this is OSC0 frequency (16MHz).
