Flow control
IP178C/IP178CH
jams or pauses a port, which causes output queue over the threshold. Its link partner
will defer transmission after detecting the jam or pause frame. A port of
IP178C/IP178CH
defers
transmission when it receives a jam or a pause frame.
IP178C/IP178CH
issues pause control frame (
Pause On, time slot count = 0xffff)
to remote station when the
output queue of the destination port is higher than high water mark threshold. When the output queue of
the destination port is lower than low water mark threshold,
IP178C/IP178CH
issues pause control frame
(
Pause Off, time slot count = 0)
to restart transmition. Besides,
IP178C/IP178CH
provides an additional
protect function, when it issues
continuous 16 times of Pause ON
frame (network abnormal), no more
Pause
ON
frame will be send.
When CoS is enabled,
IP178C/IP178CH
may disable the flow control function for a short term to
guarantee the bandwidth of high priority packets. A port disables its flow control function for 2 ~ 3
seconds when it receives a high priority packet. It doesn’t transmit pause frame or jam pattern during the
period but it still responses to pause frame or jam pattern.
The flow control function can be enabled by pulling up pin 75 X_EN or by programming MII register
30.1.10.
