TRUNC_FL
Description
This read-only field is reserved and always has the value zero.
Frame truncation length
Indicates the value a receive frame is truncated, if it is greater than this value. Should be greater than or
equal to RCR[MAX_FL].
NOTE: Truncation happens at TRUNC_FL. However, when truncation occurs, the application (FIFO)
may receive less data, guaranteeing that it never receives more than the set limit.
44.3.31 Transmit Accelerator Function Configuration (ENET_TACC)
TACC controls accelerator actions when sending frames. The register can be changed
before or after each frame, but it must remain unmodified during frame writes into the
transmit FIFO.
The TFWR[STRFWD] bit must be set to use the checksum feature.
Address: ENET_TACC is 400C_0000h base + 1C0h offset = 400C_01C0h
