SNLS610B April 2021 – November 2021 DP83561-SP
PRODUCTION DATA
Several advanced modes are available for fast link establishment. Unlike the Auto-Negotiation and Auto-MDIX mechanisms defined by the IEEE 802.3 specification, these modes are specific to the DP83561-SP. Take care when implementing these modes. For best operation, TI recommends implementing these modes with a DP83561-SP on both ends of the link.
These advanced link and crossover modes depend on the speed selected for the link. Some modes are intended for use in 1000Base-T operation. Others are intended for use in 100Base-TX operation.
Fast Link Detect functionality can be configured using the Configuration Register 3 (CFG3), address 0x001E.
