请问BF609的TDM模式如何配置？

hi Shuiyuan:
SPORT defaultly work in I2S mode, when you want to let it work in TDM mode, you should download and study on BF609's hardware reference mannual through the following link:
http://www.analog.com/media/en/dsp-documentation/processor-manuals/blackfin_hwr_bf60x_rev0.5.pdf
 
Go to SPORT chapter and you can find the following information, FYI.
 
Multichannel Mode
The processor's SPORTs offer a multichannel mode of operation, which allows the SPORT to communicate in a time division multiplexed (TDM) serial system. In multichannel communications, each data word
of the serial bit stream occupies a separate channel. Each word belongs to the next consecutive channel.
For example, a 24-word block of data contains one word for each of the 24 channels.
The multichannel mode of SPORT can be selected by setting SPORT_CTL_A.OPMODE = 0 and SPORT_MCTL_
A.MCE = 1.
Up to 128 channels are available for transmitting or receiving. The SPORT can automatically select some
words for particular channels while ignoring others. In other words, each SPORT can receive or transmit
data selectively from any of the 128 channels. These 128 channels can be any 128 out of the 1024 total channels in the system. The SPORT can do any of the following on each channel:
• Transmit data ( SPORT_CTL_A.SPTRAN = 1)
• Receive data ( SPORT_CTL_A.SPTRAN = 0)
• Do nothing during inactive channels
Optionally, data companding and DMA transfers can be used in multichannel mode on both primary and
secondary data lines.
The SPORT multichannel select registers ( SPORT_CS0_A) must be programmed before enabling SPORT
operation for multichannel mode. This is especially important in DMA data unpacked mode, since the
SPORT data buffers begin operation immediately after the SPORT data lines are enabled. The SPORT_
MCTL_A.MCE must also be enabled prior to enabling SPORT operation.

Multichannel mode operates completely independently and each SPORT uses its own serial clock and
frame sync signal either internally generated or externally provided.
 
Have a try!
Good luck!

hi Henry:
Thanks a lot! I will look up it .
And I am wondering if there has some examples code about our question, which reallly helps me a lot, as a newcomer to this.
Best wishes!
