15.5.4.2.1
The eTSEC examines received symbols looking for the seven bit ‘comma’ string embedded in some
special symbols. Both the idle ordered_set and the Configuration ordered_set contain a symbol which has
the comma. Once a certain number of codes with comma are detected, the eTSEC is considered to have
acquired synchronization.
15.5.4.2.2
Once synchronization is acquired, ordered_sets are decoded. If Configuration ordered_sets are received,
the eTSEC decodes the two octet data field and the sixteen-bit Configuration data is stored and used to
Auto-Negotiate with the link partner. in the Receive Configuration Register (RXCR[15:0]) an internal
register used to receive all the link partners informations and used to compare to local ability during
negotiation. Not visible to user. If, during Auto-Negotiation an invalid symbol is detected,
Auto-Negotiation re-starts. After Auto-Negotiation is completed the TBI MII Status Register SR[AN
done] in set. In this mode, packets may be received from the link partner.
15.5.4.3
This section describes the TBI MII registers. All of the TBI registers are 16 bits wide. The TBI registers
are accessed at the offset of the TBI physical address. The eTSEC’s TBI physical address is stored in the
TBIPA register. Writing to the TBI registers is performed in a way similar to writing to an external PHY,
using the MII management interface. Using TBIPA in place of the PHY address, in the MIIMADD[PHY
Address] field, and setting the MIIMADD[Register Address] to the appropriate address offset that
corresponds to the register that one wants to read or write (see
MIIMCOM[read cycle]) or write (writing to MIIMCON[PHY control]) to the TBI block. Refer to the TBI
physical address register in
MII register set in
registers and are only used for test and control of the eTSEC TBI block. The TBI’s TBI control register
(TBI) is for configuring the eTSEC ten-bit interface block. However, because this TBI block has an MII
management interface (just like any other PHY), it has an IEEE 802.3 register called the control register
(CR).
