External UTC/DRU channels which are managed by the UDMA follow a modified teardown sequence which is as follows:
Step | Description | module.mregion.register.field |
---|---|---|
1 | Initiate UDMA-C external TX channel teardown | udma.tchanrt.tchanrt[chan]_trt_ctl.tx_tx_teardown = 1 |
2 | Initiate UTC-DRU thread teardown | psil.gcfg.enable.tdown(bit 30) = 1 (via psilcfg proxy |
3 | Wait for UDMA-C external TX channel enable to be 0 | udma.tchanrt.tchanrt[chan]_trt_ctl.tx_enable == 0 |
