This register controls the transmit-side configuration of the Any-PHY/UTOPIA
Interface
TA_ANY-PHY_EN
Enables Any-PHY mode for the transmit side interface:
0) UTOPIA-2 Multi-Address Slave
1) Any-PHY mode.
TA_EVEN_PAR
Determines the generated parity across data bytes/words received by the
Any-PHY/UTOPIA transmit Interface.
0) Odd parity
1) Even parity.
TA_16_BIT_MODE
When set, the TX Any-PHY/UTOPIA interface operates in 16-bit mode.
0) 8-bit mode
1) 16-bit mode
TA_PREPEND:
When set, a single 2-byte prepend is expected on the Any-PHY/UTOPIA
transmit interface. This prepend is indepent of the address prepend used for
Any-PHY mode. The prepend is ignored, but the capability is provided to
enhance interoperability.
