General Notes to Receive Commands:
1. After a pulse at the reset pin a channel having a time slot with RTI = 0 should be issued
2. When it is supposed to be used it should be issued a receive initialize command
3. To shut down a channel in receive direction one should first set it into the receive abort
4. Before changing the MODE, CRC, CS, TRV, INV, TFLAG bits of a channel or its RTI
5. To revive a channel after it has been shut down one should use the receive
6. To switch to a new starting point of a receive descriptor chain one should preferably
7. To issue channel commands not affecting the receive side one should issue

only the serial interface)

TI = 0, TO = 0, TA = 1 (clears a previous transmit abort or transmit off condition, affects
only the DMA interface)
This abort is performed in the DMA controller and does not interfere with the current
transmission on the serial interface and the transfer between the TF and TB. If this
abort is detected the current descriptor is suspended and the frame or data transferred
to the TB is aborted. The next frame beginning in the transmit descriptor (FTDA)
defined in the channel specification of the CCS will be started immediately.
– a receive clear command if neither a receive off nor a receive abort condition is set
– a receive off command if a receive off condition is set
– a receive abort command if a receive abort condition is set.
