TCD Control and Status
| START | Channel Start 0 (NO_START): Channel is not explicitly started 1 (START): Channel is explicitly started via a software initiated service request |
| INTMAJOR | Enable an interrupt when major iteration count completes. 0 (DISABLED): End of major loop interrupt is disabled 1 (ENABLED): End of major loop interrupt is enabled |
| INTHALF | Enable an interrupt when major counter is half complete. 0 (DISABLED): Half-point interrupt is disabled 1 (ENABLED): Half-point interrupt is enabled |
| DREQ | Disable Request 0 (NO_CLEAR): The channel’s ERQ field is not affected 1 (CLEAR): The channel’s ERQ field value changes to 0 when the major loop is complete |
| ESG | Enable Scatter/Gather Processing 0 (NORMAL): The current channel’s TCD is normal format 1 (SCATTER): The current channel’s TCD specifies a scatter gather format |
| MAJORELINK | Enable channel-to-channel linking on major loop complete 0 (DISABLED): Channel-to-channel linking is disabled 1 (ENABLED): Channel-to-channel linking is enabled |
| ACTIVE | Channel Active |
| DONE | Channel Done |
| MAJORLINKCH | Major Loop Link Channel Number |
| BWC | Bandwidth Control 0 (DISABLED): No eDMA engine stalls 2 (STALL4): eDMA engine stalls for 4 cycles after each R/W 3 (STALL8): eDMA engine stalls for 8 cycles after each R/W |
