UTOPIA Transmit bus parity (TPRTY) signal.
The transmit parity (TPRTY) signal indicates the
parity of the TDAT[15:0] bus. A parity error is
indicated by a status bit and a maskable interrupt.
Cells with parity errors are inserted in the transmit
stream, so the TPRTY input may be unused. Odd
or even parity selection is made using the RXPTYP
register bit.
TPRTY is considered valid only when TENB is
simultaneously asserted and the S/UNI-STAR is
selected via TADR[2:0].
TPRTY is sampled on the rising edge of TFCLK.
POS-PHY Transmit bus parity (TPRTY) signal.
The transmit parity (TPRTY) signal indicates the
parity of the TDAT[15:0] bus. A parity error is
indicated by a status bit and a maskable interrupt.
Packets with parity errors are inserted in the
transmit stream, so the TPRTY input may be
unused. Odd or even parity selection is made using
the RXPTYP register bit. TPRTY is considered valid
only when TENB is simultaneously asserted and
the S/UNI-STAR is selected via TADR[2:0].
TPRTY is sampled on the rising edge of TFCLK
UTOPIA Transmit Start of Cell (TSOC) signal.
The transmit start of cell (TSOC) signal marks the
start of cell on the TDAT bus. When TSOC is high,
the first word of the cell structure is present on the
TDAT bus. It is not necessary for TSOC to be
present for each cell. An interrupt may be
generated if TSOC is high during any word other
than the first word of the cell structure.
TSOC is considered valid only when TENB is
simultaneously asserted and the S/UNI-STAR is
selected via TADR[2:0].
TSOC is sampled on the rising edge of TFCLK.
