Received Length Field Mismatch Register
Name:
EMAC_RLE
Address:
0xFFFBC088
Access:
Read-write
• RLFM: 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 network configuration register. Frames containing a type ID in bytes
13 and 14 (i.e., length/type ID
length field. Checking is enabled through bit 16 of the network configuration register. 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.
