Description
TMOD[1:0] Transmit Word Modulo.
32-bit Multi-PHY mode: TMOD[1:0]
indicates the valid data bytes of TDAT[31:0].
During transmission, TMOD[1:0] should
always be “00” until the last double word is
transferred on TDAT[31:0]. TMOD[1:0]
specifies the valid bytes of TDAT when
TEOP is asserted:
TMOD[1:0] – Valid Bytes of TDAT
00 = 4 bytes [31:0]
01 = 3 bytes [31:8]
10 = 2 bytes [31:16]
11 = 1 byte [31:24]
TENB must be asserted simultaneously for
TMOD[1:0] to be valid.
4 x 8 Single-PHY mode: MOD[1:0] is not
required.
Transmit Start of Transfer.
32-bit Multi-PHY mode: TSX asserted with
TENB = 1 indicates that the PHY address is
present on TDAT[7:0]. The valid values on
TDAT[7:0] are 3, 2, 1, and 0. When
TENB = 0, TSX is not used by the PHY
device.
Note:
4 x 8 Single-PHY mode: TSX is not used.
TADR[1:0] Transmit PHY Address.
The value on TADR[1:0] selects one of the
PHY ports that drives the PTPA signal after
the rising edge of TFCLK.
DTPA_0:3 Direct Transmit Packet
Available.
A direct status indication for transmit FIFOs
of ports 0:3.
When High, DTPA indicates that the amount
of data in the TX FIFO is below the TX FIFO
High watermark. When the High watermark
is crossed, DTPA transitions Low to indicate
that the TX FIFO is almost full. It stays Low
until the amount of data in the TX FIFO
goes back below the TX FIFO Low
watermark. At this point, DTPA transitions
High to indicate that the programmed
number of bytes are now available for data
transfers.
Note:
DTPA is updated on the rising edge of
TFCLK.
Only TDAT[1:0] are relevant; all
other bits are “Don’t Care”.
