Transmit End of Packet. These pins are used only in U2+
and U3+ (packet) modes. This signal indicates that the last
word of a packet is on the TxDATA[D:A][15:0] bus.
TxEOP[D:A] is valid only when TxENB[D:A] is asserted, and
is sampled on the rising edge of TxCLK[D:A].
In U3+ (32-bit mode), only the TxEOP[A] input pin of port A
is used to indicate the end of the incoming packet.
Transmit Error. These pins are used only in U2+ and U3+
(packet) modes. TxERR[D:A] is only used in packet modes,
and indicates that the current packet is to be aborted and
discarded, if possible. TxERR[D:A] is only valid when
TxEOP[D:A] and TxENB[D:A] are asserted, and is sampled
on the rising edge of TxCLK[D:A].
In U3+ (32-bit mode), the TxERR[A] and the TxERR[B] input
pin of port A is used to indicate an error on the incoming
packet.
Receive Address. Receive address is driven to the MPHY
to poll and select the appropriate MPHY channel.
Note: The address for each channel is configured by the
Receive Data Channel A. Used to transport data out of the
UTOPIA PHY Rx block. RxDATA[A][15:0] is only valid when
RxENB[A] is asserted, and is updated on the rising edge of
RxCLK[A]. Note that RxDATA[A][15:0] is used in various
UTOPIA modes. In U2 or U2+, all 16 bits are valid. In U3 or
U3+ (8-bit mode), only bits 15 to 8 are valid.
In U3 or U3+ (32-bit mode), RxDATA[A][15:0] forms the most
significant 16 bits of the combined data bus (bits 31 to 16),
and RxDATA[B][15:0] forms the least significant 16 bits of the
combined data bus (bits 15 to 0).
Note: [15:0] refers to a 16-bit data bus (15 = MSB, 0 = LSB).
