Re-
26.4.33 ENET MAC Accelerator Transmit Function Configuration
Transmit Accelerator function configuration. Control accelerator actions to be performed
when sending frames. The register can be changed before or after each frame, but must stay
unmodified during frame write into the transmit FIFO.

Transmit Inter Packet Gap. Set, in Bytes, the IPG between transmitted Frames. Can be set to any value
between 8 and 27. If set to a Value below 8, the IPG is 8, if set to any value above 27, the IPG is 27.
Reserved bits. Write as 0.
Frame Truncation Length. Set the value from which a receive Frame is truncated (if greater than this value).
Should be a value greater or equal to RCR(MAX_FL).
Note: Truncation happens at TRUNC_FL, however when truncation occured, the application (FIFO) may
receive less data, guaranteeing that it will never receive more than the set limit.
