Operation
MHz clock. This divider is located in the CLKCTRL module where all the system clocks
are generated; the resultant clock (pcm_spdif_clk) is the output to the SPDIF module to be
used for data transmission.
Programming the HW_SPDIF_SRR register automatically generates the right frequency of
pcm_spdif_clk from the divider in the clock controller block. There are no separate registers
to control these dividers. Make sure that the CLKGATE bit in HW_CLKCTRL_SPDIF is
cleared before starting the transmission.
The SPDIF module receives data by one of two methods:
Once provided by the DMA, the received data is placed in a 2x24 word FIFO for each
channel, left and right. At initialization, the FIFO is filled before SPDIF data transfer occurs.
After this, data is requested whenever this FIFO has an empty entry or at a nominal rate
corresponding to the programmed sample- rate in HW_SPDIF_SRR.

• Software-directed PIO writes to the HW_SPDIF_DATA register
• Appropriate programming of the DMA-engine. (See
for a detailed description of the DMA module and how to perform DMA data transfers
to/from modules and memory.)
