LAN9353
10.7.2.5 Port x MAC Receive 65 to 127 Byte Count Register (MAC_RX_65_TO_127_CNT_x)
Register #:
Port0: 0412h
Port1: 0812h
Port2: 0C12h
Size:
32 bits
This register provides a counter of received packets between the size of 65 to 127 bytes. The counter is cleared upon
being read.
Bits
Description
31:0 RX 65 to 127 Bytes
Count of packets (including bad packets) that have between 65 and 127
bytes.
Note: This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100 Mbps is approximately 487 hours.
Type
RC
Default
00000000h
Note: A bad packet is defined as a packet that has an FCS or Symbol error. For this counter, a packet that is not
an integral number of bytes is rounded down to the nearest byte.
10.7.2.6 Port x MAC Receive 128 to 255 Byte Count Register (MAC_RX_128_TO_255_CNT_x)
Register #:
Port0: 0413h
Port1: 0813h
Port2: 0C13h
Size:
32 bits
This register provides a counter of received packets between the size of 128 to 255 bytes. The counter is cleared upon
being read.
Bits
Description
31:0 RX 128 to 255 Bytes
Count of packets (including bad packets) that have between 128 and 255
bytes.
Note: This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100 Mbps is approximately 848 hours.
Type
RC
Default
00000000h
Note: A bad packet is defined as a packet that has an FCS or Symbol error. For this counter, a packet that is not
an integral number of bytes is rounded down to the nearest byte.
