This is a special mode to improve bandwidth. When enabled, the channel waits until the FIFO is less than half full to fetch the data from the source peripheral, and waits until the FIFO is greater than or equal to half full in order to send data to the destination peripheral. Because of this, the channel can transfer the data using bursts, which eliminates the need to arbitrate for the AHB master interface in each single AHB transfer. When this mode is not enabled, the channel waits only until the FIFO can transmit or accept a single AHB transfer before it requests the master bus interface.
