Codec and McBSP

Hi to all,

I am a DSK 6713 user. I have been reading many documents about codec and mcbsp programming. I thought that codec and mcbsp were internally connected, so that it is neccessary to program both peripherals. But I have seen an example which uses only codec to connect the board to headphones.

Can I use these peripherals by separate or I need both to work??

Thanks for all,

McBSP means "multichannel buffered serial port", a 6713 onchip peripheral. On the
DSK board two (2) McBSP ports are connected to the AIC23B codec chip, one control
port and one data port. To program the codec, a series of words is written by DSP
code to registers in the codec, using the control port.

The AIC23B has 2 input channels and 2 output (a "stereo codec"). The headphones
connector is tied to one of the output channels.
