Hello, i'm trying to interface a NAU8811 to i2s0 on a LPC4330.

The codec has an i2c interface with 4 connections. A shared bit clock, data in/out and a channel clock(WS).
A MCLK is generated internally based on the BCLK.

Is it possible to use one clock and WS for both tx and rx on the 4330 instead of a seperate TX_SCK,TX_WS and RX_SCK,RX_WS?

Thanks.
