JAJSC32E September 2012 – June 2019 DP83848-EP
PRODUCTION DATA.
It is important to note that if the DP83848-EP has been initialized upon power-up as a non-auto-negotiating device (forced technology), and it is then required that Auto-Negotiation or re-Auto-Negotiation be initiated via software, bit 12 (Auto-Negotiation Enable) of the Basic Mode Control Register (BMCR) must first be cleared and then set for any Auto-Negotiation function to take effect.
