Function
The outgoing data parity (ODP) signal carries
the parity of the outgoing data stream, OD[7:0].
Odd parity is selected by setting the OOP
register bit high, and even parity is selected by
setting the OOP bit low. ODP is updated on the
rising of SCLK in outgoing byte interface mode
(OBMODE set high) and on the rising edge of
NSCLK in outgoing nibble interface mode
(OBMODE set low).
The outgoing tributary payload active (OTPL)
signal marks the bytes carrying the tributary
payload.
In outgoing byte interface mode (OBMODE set
high), OTPL is set high to mark each tributary
payload byte on the OD[7:0] bus. In floating
mode, OTPL contains valid data only for bytes in
the VC3 or VC4 virtual container(s), or the
STS-1 synchronous payload envelopes. Its
contents should be ignored for bytes in the
transport overhead. In locked mode, OTPL is
set low for transport overhead. OTPL is updated
on the rising edge of SCLK.
In outgoing nibble interface mode (OBMODE set
low), OTPL is set high to mark each tributary
payload byte on the OD[3:0] bus. In floating
mode, OTPL contains valid data only for bytes in
the VC3 or VC4 virtual container(s), or the
STS-1 synchronous payload envelopes. Its
contents should be ignored for bytes in the
transport overhead. In locked mode, OTPL is
set low for transport overhead. OTPL is updated
on the rising edge of NSCLK.
