What do you mean when you say "PCM short frame sync" and "PCM long frame sync"?
Sorry for the late reply, I was away.
What I mean by short/long frame sync is: the frame sync lasts for 1 bit/1 word wide.
Eg.: For short frame sync, we get a frame sync signal for 1 clock before the first bit on the RX/TX.
It is different from I2S mode where the frame sync is inverted and the transition starts 1 clock before the bits and lasts till bit 1.
I'm sorry but I still have no idea what you're talking about. You've described PCM mode but not explained what "short frame sync" and "long frame sync" mode are.
This diagram may explain things better: http://picpaste.com/pcm_fs-7dBlrkuW.png
