Description
Center side only
Use to select pattern for MC loop back packet
0000_0000 : 64 bytes DA; Unicast Data: 55AA
0000_0001 : 1518 bytes DA; UnicastData: 55AA
0000_0010 : 64 bytes DA; Broadcast Data: 55AA
0000_0100 : 1518 bytes DA; Broadcast Data: 55AA
0000_1000 : 64 bytes DA; Unicast Data: 0F0F
0001_0000 : 1518 bytes DA; Unicast Data: 0F0F
0010_0000 : 64 bytes DA; Broadcast Data: 0F0F
0100_0000 : 1518 bytes DA; Broadcast Data: 0F0F
1000_0000 : 1518 bytes DA; Broadcast Data: FF00
other values : N/A
where the packet’s:
DA is [Register #52h]:[Register #53h]:[Register
#54h]:[Register #55h]:[Register #56h]: ([Register #57h] + 1).
And the last byte ([Register #57h] + 1) increments repeatedly
by 1 for the next loop back packet.
SA is [Register #52h]:[Register #53h]:[Register
#54h]:[Register #55h]:[Register #56h]: [Register #57h]
Type/length is 0x0800h
Description
Center side only
This counter is incremented when loop back packet has CRC
error.
0000_0000 : No CRC error received
0000_0001 : 1 CRC error received
:
1111_1111 : 255 CRC errors received
This counter is cleared when 0x00h is written to reg. 0x44h.
Description
Center side only
This counter is incremented when loop back packet has
timeout.
0000_0000 : No timeout occurred
0000_0001 : 1 timeout occurred
:
1111_1111 : 255 timeouts occurred
This counter is cleared when 0x00h is written to reg. 0x44h.
