45.6.26.5 Frames Received OK Register
Name:
EMAC_FRO
Address:
0xF802C04C
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 memory. 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.

45.6.26.6 Frames Check Sequence Errors Register
Name:
EMAC_FCSE
Address:
0xF802C050
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.
