[ts-7000] TS7250 and I2S

["Vijay" <>]

Hi friends,
 Sorry if this has been answered already. I am using a TS-7250 and a
Cirrus Logic CS4341A DAC. I am trying to connect the two using an I2S
bus. But, looks like the Ts-7250 does not export any of the I2S pins
to an external header pin. [ I am just prototyping right now ]

 Namely, 
PIN 154 - ARST
PIN 107 - ABITCLK
PIN 89  - ASYNC
PIN 156 - ASDI
PIN 92  - ASDO

 1. Is my understanding of the 7250 limitation correct?
 2. Any suggestions on how I can interface the 7250 to a DAC chip
using I2S protocol? Would bitbanging using one of the DIO ports be a
viable solution?

Any help in this regard is appreciated.
Thanks,
-Vijay
