36.6.27.5 Frames Received OK Register
Name: EMAC_FRO
Address: 0xFFFBC04C
Access: Read-write
• FROK: Frames Received OK
A 24-bit register counting the number of good frames received, i.e., address recognized and successfully copied to mem-
ory. A good frame is of length 64 to 1518 bytes (1536 if bit 8 set in network configuration register) and has no FCS,
alignment or receive symbol errors.
36.6.27.6 Frames Check Sequence Errors Register
Name: EMAC_FCSE
Address: 0xFFFBC050
Access: Read-write
• FCSE: Frame Check Sequence Errors
An 8-bit register counting frames that are an integral number of bytes, have bad CRC and are between 64 and 1518 bytes
in length (1536 if bit 8 set in network configuration register). This register is also incremented if a symbol error is detected
and the frame is of valid length and has an integral number of bytes.
