Finish MCU bootloader code for 8/16-bit ATMEL AVR XMEGA A1U Microcontroller

Job Description

hi,

we have programmed a microcontroller to relay a digital audio signal to three separate digital audio chips.

the code is almost done but need to change the GPIO settings and recompile the code.

here are the directions:

Could you please change the following GPIOs in the ATMEL code...

DAC_SEL2 from 1 to 0
DAC_SEL3 from 1 to 0

... this will allow the CP2114 to boot-up to Index 3, which I've pre-programmed to have our CP2114 settings in it. The other two DAC select GPIOs remain the same.

The GPIOs which change are shown below...
