I'd like to connect a microphone like this one http://www.invensense.com/wp-content/uploads/2015/02/ICS-43432_DS.pdf, that is provided with a I2S interface, to the SSI interface of the I.MX6.
I saw in the i.MX 6Dual/6Quad Applications Processor Reference Manual, Rev. 3, 07/2015, that in Synchronous Mode (4-Wire Interface), each port will be a 4-wire interface (that is, RXD, TXD, TXC, TXFS). In this setup, receive data timing is determined by TXC and TXFS.
So, I'm thinking to use the following configuration:
- TXC to provide the clock signal for the microphone
- TXFS to provide the Word Select
- RXD to receive the data from the microphone
- TXD Not used!
Is it correct?
Thanks in advance!
