– Selects the backoff mode. When
′
1
′
the standard backoff process is changed by
resetting the collision counter after valid packet is received, instead of resetting
after successful transmission. When
′
0
′
the standard backoff process is executed.
- Default

′
– If set to
′
1
′
then no backoff will be executed when a half duplex port is in flow
control mode. When
′
0
′
, an aggressive backoff will be executed (recommended).
– When set to
′
1
′
the backpressure operation will be executed for a number of
slot times determined by Flow Control Pause Value setting or until an XON
command is received. When
′
0
′
the backpressure will be also stopped after
reaching a number of consecutive collisions specified using
BacKPrLv
field.
– Specifies the number of consecutive collisions that will determine TC6216M
to cancel the backpressure (see the setting above).
- Default

– When is set the full duplex flow control resolution will be executed. This means
that if the link partner does not advertise the flow control capability, the switch
will not execute the flow control on transmission side. As result no flow control
PAUSE frame will be generated, but transmission will be stopped if a valid flow
control frame is received). If
FCOpt
is not set then the full duplex flow control
will always be in effect unless deactivated by
ConfigRegPx[4] (DsFulDpxFC)
