Pin - Channel 0; DS3/E3 Frame Synchronizer Framing
Pulse Output Pin - Channel 4:
The function of this output pin depends upon whether or not
theSTS-3/STM-1 Telecom Bus Interface for Channel 0 has
been enabled.
If STS-3/STM-1 Telecom Bus (Channel 0) has been enabled
- STS-3/STM-1 Receive Telecom Bus - Parity Output Pin:
This output pin can be configured to function as one of the fol-
lowing.
1. The EVEN or ODD parity value of the bits which are output
via the STS3RXD_D_0[7:0] output pins.
2. The EVEN or ODD parity value of the bits which are being
output via the STS3RXD_D_0[7:0] output pins and the states
of the STS3RXD_PL_0 and STS3RXD_C1J1_0 output pins.
This output pin will ultimately be used (by drop-side circuitry) to
verify the verify of the data which is output via the STS-3/STM-
1 Telecom Bus Interface associated with Channel 0.

If STS-3/STM-1 Telecom Bus (Channel 0) is disabled -
RxDS3FP_4 (Receive DS3 Frame Pulse Input/Output -
Channel 4):
If the STS-3/STM-1 Telecom Bus (Channel 0) is disabled and if
the DS3/E3 Framer block is enabled then this pin will function
as the Receiving Framing Reference output pin. In this mode,
the Frame Synchronizer block (associated with Channel 4) will
pulse this output pin "High" for one DS3/E3 bit-period, coinci-
dent with the first bit (within a given DS3 or E3 frame) being
output via the DS3/E3/STS1_Data_OUT_4 output pin.

: Any one of these configuration selections can be made
: This pin is inactive if the Frame Synchronizer block,
by writing the appropriate value into the Telecom Bus
Control Register (Indirect Address = 0x00, 0x3B),
(Direct Address = 0x013B).
associated with Channel 4 is by-passed.
