•FCMODE: Flow Control Mode
Determines when source transaction requests are serviced when the Destination Peripheral is the flow controller.
0 = Source transaction requests are serviced when they occur. Data pre-fetching is enabled.
1 = Source transaction requests are not serviced until a destination transaction request occurs. In this mode the amount of data
transferred from the source is limited such that it is guaranteed to be transferred to the destination prior to block termination by
the destination. Data pre-fetching is disabled.
