Thanks, Dafydd Roche.
I could see MSB's and LSB's location , compare with WS and SCK signal, in Phillips I2S specification.
Even though there are no mention about ratio, The "Basic Interface Timming" figure say NO 64 CLOCK PULSES for only 24BIT DATA.
I selected PCM4204 for 24bit resolution and 4 channel.
For McASP of C6743 and for get the 4 ch interface, I have to change PCM4204 from master mode to slave mode, and change C6743 program also, right?
I'm worrying about my exhibition to VIP the day after tomorrow.

Suno.
