1 Enable the TBI to transmit the jitter test patterns defined in IEEE 802.3z 36A.
Selects the jitter pattern to be transmitted in diagnostics mode. Encoding of this field is shown in the
following table. Default is 00.
Reserved
Used in conjunction with jitter (pattern) select and jitter (diagnostic) enable; set this field to the desired
custom pattern which is continuously transmitted. Its default is 0x000.
