40.6.33 Received Length Field Mismatch Register

EMAC_RLE is an EMAC statistics register. It resets to zero on a read and sticks at all ones when it counts to its maximum value. It should be read frequently enough to prevent loss of data.

Bits 7:0 – RLFM[7:0] Receive Length Field Mismatch

An 8-bit register counting the number of frames received that have a measured length shorter than that extracted from its length field. Checking is enabled through bit 16 of the EMAC_NCFGR. Frames containing a type ID in bytes 13 and 14 (i.e., length/type ID = 0x0600) are not counted as length field errors, neither are excessive length frames.
