Ethernet Media Access Controller (EMAC) Registers

5.50.26 Transmit Octet Frames Register (TXOCTETS)

The total number of bytes in all good frames transmitted on the EMAC. A good frame is defined as having all of the following:

∙Any data or MAC control frame that was destined for any unicast, broadcast, or multicast address

∙Was any length

∙Had no late or excessive collisions, no carrier loss, and no underrun

5.50.27Transmit and Receive 64 Octet Frames Register (FRAME64)

The total number of 64-byte frames received and transmitted on the EMAC. Such a frame is defined as having all of the following:

∙Any data or MAC control frame that was destined for any unicast, broadcast, or multicast address

∙Did not experience late collisions, excessive collisions, underrun, or carrier sense error

∙Was exactly 64-bytes long. (If the frame was being transmitted and experienced carrier loss that resulted in a frame of this size being transmitted, then the frame is recorded in this statistic).

CRC errors, alignment/code errors, and overruns do not affect the recording of frames in this statistic.

5.50.28 Transmit and Receive 65 to 127 Octet Frames Register (FRAME65T127)

The total number of 65-byte to 127-byte frames received and transmitted on the EMAC. Such a frame is defined as having all of the following:

∙Any data or MAC control frame that was destined for any unicast, broadcast, or multicast address

∙Did not experience late collisions, excessive collisions, underrun, or carrier sense error

∙Was 65-bytes to 127-bytes long

CRC errors, alignment/code errors, underruns, and overruns do not affect the recording of frames in this statistic.

5.50.29 Transmit and Receive 128 to 255 Octet Frames Register (FRAME128T255)

The total number of 128-byte to 255-byte frames received and transmitted on the EMAC. Such a frame is defined as having all of the following:

∙Any data or MAC control frame that was destined for any unicast, broadcast, or multicast address

∙Did not experience late collisions, excessive collisions, underrun, or carrier sense error

∙Was 128-bytes to 255-bytes long

CRC errors, alignment/code errors, underruns, and overruns do not affect the recording of frames in this statistic.

5.50.30 Transmit and Receive 256 to 511 Octet Frames Register (FRAME256T511)

The total number of 256-byte to 511-byte frames received and transmitted on the EMAC. Such a frame is defined as having all of the following:

∙Any data or MAC control frame that was destined for any unicast, broadcast, or multicast address

∙Did not experience late collisions, excessive collisions, underrun, or carrier sense error

∙Was 256-bytes to 511-bytes long

CRC errors, alignment/code errors, underruns, and overruns do not affect the recording of frames in this statistic.
