Log number 007: (LSI) Receiving data of unusual size
The number of frames whose frame length was abnormal.
Log number 008: (LSI) Bubble errors
Unused.
Log number 009: (LSI) Collision errors
Number of collision errors.
Log number 010: (LSI) Missed packet errors
The number of packets that were lost during operation because the communication LSI's
internal buffer was full.
Log number 011: (LSI) Memory errors
Number of communication LSI internal memory access errors detected.
Log number 012: (LSI) Late collision
The number of late collisions (i.e., collisions detected during the transmission of the 64th
or subsequent byte of data after the preamble) that occurred during transmission.
Log number 013: (LSI) Sent buffer errors
The number of times the communication buffer became full.
Log number 014: (LSI) Undershoot flow error
The number of send-buffer underflow errors that occurred during transmission.
Log number 015: (LSI) Carrier losses

during transmission.
Log number 017: (LSI) Framing errors
The number of framing errors that occurred during reception.
Log number 018: (LSI) Received overflow
The number of receive-buffer overflows that occurred during reception.
Log number 019: (LSI) CRC errors
