The Inter-IC Sound Controller (I2SMCC) provides a 5-wire, bidirectional, synchronous, digital audio link to external audio devices: I2SMCC_DIN, I2SMCC_DOUT, I2SMCC_WS, I2SMCC_CK, and I2SMCC_MCK pins. The I2SMCC complies with the Inter-IC Sound (I2S) bus specification and supports a Time Division Multiplexed (TDM) interface with external multi-channel audio codecs. The I2SMCC consists of a receiver, a transmitter and a common clock generator that can be enabled separately to provide Master, Slave or Controller modes with receiver and/or transmitter active. DMA Controller channels, separate for the receiver and for the transmitter, allow a continuous high bit rate data transfer without processor intervention to the following: - Audio CODECs in Master, Slave, or Controller mode - Stereo DAC or ADC through a dedicated I2S serial interface - Multi-channel or multiple stereo DACs or ADCs, using the TDM format This IP is embedded in Microchip's new sam9x60 SoC.
