怎么理解McBSP的128个通道?



看McBSP手册到5.1节说MCBSP支持128个通道,不能理解这128通道是什么意思,怎么引出这么多通道的?

  • 分为8个Block,每个Block有16个通道。

    Receive current block indicator. RCBLK indicates which block fo 16 channels is involved in the
    current McBSP reception:
    0 Block 0: channels 0 through 15
    1h Block 1: channels 16 through 31
    2h Block 2: channels 32 through 47
    3h Block 3: channels 48 through 63
    4h Block 4: channels 64 through 79
    5h Block 5: channels 80 through 95
    6h Block 6: channels 96 through 111
    7h Block 7: channels 112 through 127
