LAN9353
10.7.2.7 Port x MAC Receive 256 to 511 Byte Count Register (MAC_RX_256_TO_511_CNT_x)
Register #:
Port0: 0414h
Port1: 0814h
Port2: 0C14h
Size:
32 bits
This register provides a counter of received packets between the size of 256 to 511 bytes. The counter is cleared upon
being read.
Bits
Description
31:0 RX 256 to 511 Bytes
Count of packets (including bad packets) that have between 256 and 511
bytes.
Note: This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100 Mbps is approximately 1581 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.
10.7.2.8 Port x MAC Receive 512 to 1023 Byte Count Register (MAC_RX_512_TO_1023_CNT_x)
Register #:
Port0: 0415h
Port1: 0815h
Port2: 0C15h
Size:
32 bits
This register provides a counter of received packets between the size of 512 to 1023 bytes. The counter is cleared upon
being read.
Bits
Description
31:0 RX 512 to 1023 Bytes
Count of packets (including bad packets) that have between 512 and 1023
bytes.
Note: This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100 Mbps is approximately 3047 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.
