Section 18 Serial Sound Interface (SSI)
When the SSI module acts as a transmitter, each word written to SSITDR is transmitted to the
serial audio bus in the order they are written. When the SSI module acts as a receiver, each word
received by the serial audio bus is read in the order received from the SSIRDR register.
Figures 18.7 to 18.9 show how 4, 6 and 8 channels are transferred to the serial audio bus. Note that
there are no padding bits in the first example, the second example is left-aligned and the third is
right-aligned. This selection is arbitrary and is just for demonstration purposes only.
