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 a PLL (or a DFLL, depending on the device) and use it as the main clock source for the synchronous clocks,
• configure a Generic Clock and output it to a GPIO pin,
• LED0 blinks endlessly.

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 can be used. This example has been tested with the following setups:

• EVK1100 evaluation kit
• EVK1105 evaluation kit
• EVK1101 evaluation kit
• EVK1104 evaluation kit
• STK600 starter kit with the RCUC3L0 routing card
• AT32UC3L-EK evaluation kit
• AT32UC3C-EK evaluation kit
• STK600 starter kit with the RCUC3D routing card

Setup Information

CPU speed: 48 MHz

• On EVK1100, check GCLK0 pin with an oscilloscope, the frequency should be 48MHz. On EVK1100, GCLK_0 is pin number 51 (PB19) with AT32UC3A0512 in QFP144 package. Since LED5 is also on PB19, you should also see LED5 turn red.
• On EVK1105, check GCLK2 pin with an oscilloscope, the frequency should be 48MHz. On EVK1100, GCLK_2 is pin number 62 (PB30) with AT32UC3A0512 in QFP144 package. This pin is accessible on J16.6 on EVK1105 revB or on J17.5 on EVK1105 revC.
• On EVK1101, check GCLK2 pin with an oscilloscope, the frequency should be 48MHz. On EVK1101, GCLK_2 is pin number 30 (PA30) with AT32UC3B0256 in QFP64 package.
• On EVK1104, check GCLK1 pin with an oscilloscope, the frequency should be 48MHz. On EVK1104, GCLK_1 is pin number 43 (PB11) with AT32UC3A3256 in QFP144 package.
• On the STK600 + RCUC3L0 setup or on the AT32UC3L-EK board, check the GCLK_1_0 pin with an oscilloscope, the frequency should be 48MHz. 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; for the AT32UC3L-EK board, place the oscilloscope probe on connector PA6.
• On UC3C_EK, check GCLK0 pin with an oscilloscope, the frequency should be 48MHz. On UC3C_EK, GCLK_0 is pin number 54 (PB22) with AT32UC3C0512C in QFP144 package.
• On the STK600 + RCUC3D setup , check the GCLK_0 pin with an oscilloscope, the frequency should be 36MHz. GCLK_0 is GPIO pin 3/pin pa03. For the RCUC3D routing card, this pin is mapped on STK600.PORTA.PA3.
• Check that LED0 blinks (whatever the board).
