Direct Memory Access (DMA)
the programmer’s model, but it would be unclear whether the actual link was made before the channel
retired.
The following coherency model is recommended when executing a dynamic channel link or dynamic
scatter/gather request:
This same coherency model is true for dynamic scatter/gather operations. For both dynamic requests, the
TCD local memory controller forces the TCD.MAJOR.E_LINK and TCD.E_SG bits to 0 on any writes to
a channel’s TCD.WORD7 after that channel’s TCD.DONE bit is set, indicating the major loop is complete.
9-42
1. Set the TCD.MAJOR.E_LINK bit.
2. Read back the TCD.MAJOR.E_LINK bit.
3. Test the TCD.MAJOR.E_LINK request status.
4. If the bit is set, the dynamic link attempt was successful.
5. If the bit is cleared, the attempted dynamic link did not succeed. The channel was already retiring.
Clear the TCD.DONE bit before writing the TCD.MAJOR.E_LINK or
TCD.E_SG bits. The TCD.DONE bit is cleared automatically by the
DMA_ENGINE after a channel begins execution.
