Hi,
*Bad English alert*
I am working on mp3 player using AU6210HD IC. [Datasheet]
It's working fine by reading mp3s from USB drive and I command it through NEC remote.
Now I want to read music from sd card and command it through push buttons.
I can't find any resources on the internet.
Any help is appreciated
Ps: I use this IC because it's cheap, should I keep using it or do you recommend any other MP3 Decoder SOC??
The circuit:
- USB female port on: PIN 19 DM, PIN 18 DP
- IR receiver on: PIN 24
- Speaker on: PIN 6 LEFT, PIN 7 RIGHT
- Oscillator on: PIN 10 and 11
- Vcc : PIN 13 and 14
- GND: PIN 2
 

At first you need to know which pins are the SPI pins. SD cards support SPI communication. But from the datasheet and pinout I could not figure out which pins are the SPI pins of this IC.
