Enhanced Three-Speed Ethernet Controllers
16.3
The eTSEC’s primary operational modes are the following:
16-4
•
•
•
•
•
— Hash table match on up to 256 unicast/multicast or 512 multicast-only addresses
— Promiscuous mode
Remote network monitoring (RMON) statistics support
— 32-bit byte counters
— Carry/Overflow of counter interrupts
Backward compatibility with MPC8349E (PowerQUICC II Pro) TSEC
— PowerQUICC II Pro buffer descriptor (BD) format and rings supported
— Common register memory map, with specific exceptions:
— Reset state of eTSEC defaults to common PowerQUICC II Pro TSEC subset
— TSEC_ID register permits TSEC versus enhanced TSEC differentiation
Hardware assist for 1588 compliant timestamping
— Per packet timestamp tag for Receive
— Programmable timestamp capture for Transmit
— Recognition of PTP packet
— Periodic Pulse Generation
— Self-correcting precision timer with nano-second resolution
— Phase aligned adjustable (divide by N) clock output
— Two 64-bit alarm (future time) registers for future time comparison
Full- and half-duplex operation
This is determined by the MACCFG2 register’s full-duplex bit (MACCFG2[Full Duplex]).
Full-duplex mode is intended for use on point-to-point links between switches or end node to
switch. Half-duplex mode is used in connections between an end node and a repeater or between
repeaters.
If configured in half-duplex mode (10- and 100-Mbps operation; MACCFG2[Full Duplex] is
cleared), the MAC complies with the IEEE CSMA/CD access method.
If configured in full-duplex mode (10/100/1000 Mbps operation; MACCFG2[Full Duplex] is set),
the MAC supports flow control. If flow control is enabled, it allows the MAC to receive or send
PAUSE frames.
10- and 100-Mbps MII interface operation
The MAC–PHY interface operates in MII mode by setting MACCFG2[I/F Mode] = 01. The MII
is the media-independent interface defined by the 802.3 standard for 10/100 Mbps operation. The
speed of operation is determined by the TSECn_TX_CLK and TSECn_RX_CLK signals, which
are driven by the transceiver. The transceiver either auto-negotiates the speed, or it may be
Modes of Operation
– Out-of-sequence transmit BD not supported
– Internal DMA BD pointers and data counts not visible
– MINFLR register not supported
