The TDM transfer mode of the McASP supports the I2S format when frame is configured to have 2 slots. I2S format is specifically designed to transfer a stereo channel (left and right) over a single data pin AXRn. "Slots" are also commonly referred to as "channels". The frame width duration in the I2S format equals size of a slot. The frame signal is also referred to as "word select" in the I2S format.
The I2S protocol is illustrated on Figure 24-114.
