4.4.3.9.19 Packets Received (128-255 Bytes) Count – PRC255 (0x04064; R)
Field
PRC255
Bit(s)
Initial
Value
Description
31:0
0x0
Number of packets received that are 128-255 bytes in length.
This register counts the number of good packets received that are 128-255 bytes (from <Destination
Address> through <CRC>, inclusively) in length. Packets that are counted in the Missed Packet Count
register are not counted in this register. This register does not include received flow control packets and
increments only if receives are enabled.
4.4.3.9.20 Packets Received (256-511 Bytes) Count – PRC511 (0x04068; R)
Field
PRC511
Bit(s)
Initial
Value
Description
31:0
0x0
Number of packets received that are 256-511 bytes in length.
This register counts the number of good packets received that are 256-511 bytes (from <Destination
Address> through <CRC>, inclusively) in length. Packets that are counted in the Missed Packet Count
register are not counted in this register. This register does not include received flow control packets and
increments only if receives are enabled.
4.4.3.9.21 Packets Received (512-1023 Bytes) Count – PRC1023 (0x0406C; R)
Field
PRC1023
Bit(s)
Initial
Value
Description
31:0
0x0
Number of packets received that are 512-1023 bytes in length.
This register counts the number of good packets received that are 512-1023 bytes (from <Destination
Address> through <CRC>, inclusively) in length. Packets that are counted in the Missed Packet Count
register are not counted in this register. This register does not include received flow control packets and
increments only if receives are enabled.
4.4.3.9.22 Packets Received (1024 to Max Bytes) Count – PRC1522 (0x04070; R)
Field
PRC1522
Bit(s)
Initial
Value
Description
31:0
0x0
Number of packets received that are 1024-Max bytes in length.
This register counts the number of good packets received that are from 1024 bytes to the maximum
(from <Destination Address> through <CRC>, inclusively) in length. The maximum is dependent on
the current receiver configuration and the type of packet being received. If a packet is counted in
Receive Oversized Count, it is not counted in this register (see Section 4.4.3.9.32). This register does
