Name
This register sets number the byte cycles
for which the collision has to be applied.
The 6-bit configuration holds the value in
bytes, which applies to the minimum
length/duration of back pressure in half-
duplex mode. Flow control in the receive
path is executed by deliberately colliding
the incoming packets in half-duplex mode.
Register bits 5:0 are used alone.
Reserved
Description
When TX HDFC is enabled (half-duplex mode
only), the MAC generates deliberate collisions on
incoming packets when the RX FIFO occupancy
crosses the High Watermark (flow control).
0 = Disable TX half-duplex flow control
1 = Enable TX half-duplex flow control
0 = Disable TX full-duplex flow control [the MAC
1 = Enable TX full-duplex flow control [enables the
0 = Disable RX full-duplex flow control [the MAC
1 = Enable RX full-duplex flow control [MAC will
will not generate internally any flow control
frames based on the RX FIFO watermarks or
the Transmit Pause Control interface

partner based on the RX FIFO programmable
watermarks or the Transmit Pause Control

partner and will stop packet transmission for
