Jabber is a condition in which a station transmits for a period of time longer than the maximum permissible packet length, usually due to a fault condition. The jabber function monitors the DP83822 output and disables the transmitter if it attempts to transmit a packet of longer than legal size. A jabber timer monitors the transmitter and disables the transmission if the transmitter is active for approximately 100ms. When disabled by the Jabber function, the transmitter stays disabled for the entire time that the module's internal transmit enable is asserted. This signal must be de-asserted for approximately 500ms (unjab time) before the Jabber function re-enables the transmit outputs. The Jabber function is only available and active in 10BASE-Te mode.
