29.7.28.5 Frames Received OK Register
Register Name: FRO
Access Type: 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, BIG, in network configuration register, NCFGR, is set, 10240
if bit 3, JFRAME in network configuration register, NCFGR, is set) and has no FCS, alignment or receive symbol errors.
29.7.28.6 Frames Check Sequence Errors Register
Register Name: FCSE
Access Type: 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, BIG, in network configuration register, NCFGR, is set, 10240 if bit 3, JFRAME in network configura-
tion register, NCFGR, is set). 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.
