Function
Output F2
The outgoing data parity #1 (ODP[1]) signal
carries the parity of the outgoing STM-4 or STM-
1 #1 data stream on OD[7:0] and optionally
including the OC1J1V1[1] and the OPL[1]
signals. OC1J1V1[1] and OPL[1] can be
included in the parity calculation by setting the
corresponding INCOC1J1 and INCOPL register
bits high, respectively. Odd parity is selected by
setting the corresponding OOP register bit high,
and even parity is selected by setting the OOP
bit low.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), ODP[1] is updated on
the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), ODP[1] is updated on
the rising edge of HSCLK.
ODP[2]
Output J21
The outgoing data parity #2 (ODP[2]) signal
carries the parity of the outgoing STM-1 #2 data
stream on OD[15:8] and optionally including the
OC1J1V1[2] and the OPL[2] signals.
OC1J1V1[2] and OPL[2] can be included in the
parity calculation by setting the corresponding
INCOC1J1 and INCOPL register bits high,
respectively. Odd parity is selected by setting the
corresponding OOP register bit high, and even
parity is selected by setting the OOP bit low.
In outgoing STM-1 (STS-3) interface mode
(OHSMODEB set high), ODP[2] is updated on
the rising edge of SCLK.
In outgoing STM-4 (STS-12) interface mode
(OHSMODEB set low), ODP[2] is invalid.
