MP3 player project

[kalio]

Hi guys!

A little wile ago a friend of mine donate a bu94605kv'm from ROHM and I thought is worth trying to build my own mp3 palyer but the problems appears pretty quickly(this is my first project in embedded world)



In the archive I put the datasheet for bu94605kv and a functional speciffication file of an related IC http://www.mediafire.com/?xxrwm2l2jt9xdre

My first question is: Can i wire all the pins who need a pull-up resistor to one resistor?
Im not sure if i choose a good value for the bypass capacitor (C6 10uF).
I don't know what I have to do whit the no. 54 pin(VCDACO).In datasheet they say: Audio DAC reference voltage output.
I'll need audio amplification on the schema?
What else I'll need to add/change?

(the battery has 3.7V not 9V)
sorry for my english

Thank you in advance
