A McBSP channel is a time slot for shifting in/out the bits of one serial word. Each McBSP supports up to 128 channels for reception and 128 channels for transmission.
In the receiver and in the transmitter, the 128 available channels are divided into eight blocks that each contain 16 contiguous channels (see Table 34-8 through Table 34-10):
The blocks are assigned to partitions according to the selected partition mode. In the two-partition mode (described in Section 34.6.4), you assign one even-numbered block (0, 2, 4, or 6) to partition A and one odd-numbered block (1, 3, 5, or 7) to partition B. In the 8-partition mode (described in Section 34.6.5), blocks 0 through 7 are automatically assigned to partitions, A through H, respectively.
The number of partitions for reception and the number of partitions for transmission are independent. For example, using two receive partitions (A and B) and eight transmit partitions (A to H) is possible.
