Section 34 Serial Sound Interface (SSI)
Rev. 1.00 Oct. 01, 2007 Page 1442 of 1956

In the case of the SSI module configured as a transmitter then each word that is written to SSITDR
is transmitted in order on the serial audio bus.
In the case of the SSI module configured as a receiver each word received on the Serial Audio Bus
is presented for reading in order by SSIRDR.
Figures 34.6 to 34.8 show how 2, 3 and 4 channels are transferred on the serial audio bus.
Figures 34.6 to 34.8 show how data on multiple channels (2, 3 or 4 channels) is transferred on the
serial audio bus. Figure 34.6 shows the data transfer using no padding bits. Figure 34.7 shows the
data transfer in which data is left-aligned with padding bits. Figure 34.8 shows the data transfer in
which data is right-aligned with padding bits. This selection is purely arbitrary.
