Description
This is a 10-bit value that sets the limit for late
collision. Collisions happening at byte times
beyond the configured value are considered to be
late collisions. (Only valid in half-duplex).
Description
This is a 4-bit value that sets the limit for
excessive collisions. When the number of
transmission attempts performed for a packet
exceeds this value, it is considered to be an
excessive collision and the frame is dropped.
(Only valid in half-duplex).
Description
The 16-bit pause length inserted in the flow
control pause frame sent to the receiving
station. The value is in 512-bit times.
Description
The lowest 32 bits of the 48-bit globally
assigned multicast pause frame destination
address.
The highest 16 bits (47:32) of the globally
assigned multicast pause frame destination
address. The higher 16-bit address is
derived from bits 15:0 of this register.
