lpc2148+vs1033d

Hi,

I am trying to interface vs1033d mp3/aac decoder with LPC2148.I wrote code for testing sine test on vs1033d...but it is not working.

So, to activate the sine test these are the steps,
- Reset the VS chip
- Set the ALLOW_TESTS bit in the SCI_MODE register (register 0)
- Make sure the XCS is high (never have both XCS and XDCS low at the same time)
- Pull XDCS low
- Send the 8 byte sequence to the SPI bus
- Wait for the sending of bytes to be complete
- Pull XDCS back high
You should now hear the beep.
i m writing my code here..please check the code and help me what is wrong in it..
