Local Output Reset State (5 V Tolerant Input with Internal Pull-down).
When this input is LOW, the device will initialize with the LSTo0-15 outputs
driven high, and the LCSTo0-1 outputs driven low. Following initialization, the
Local stream outputs are always active and a high impedance state, if required
on a per-channel basis, may be implemented with external buffers controlled
by outputs LCSTo0-1.
When this input is HIGH, the device will initialize with the LSTo0-15 outputs at
high impedance and the LCSTo0-1 outputs driven low. Following initialization,
the Local stream outputs may be set active or high impedance using the ODE
pin or on a per-channel basis with the LE bit in the Local Connection Memory.
Local Serial Output Streams 0 to 7 (5 V Tolerant Three-state Outputs with
Slew-Rate Control).
In Local Non-32 Mbps Mode, these pins output serial TDM data streams at a
data rate of:
16.384 Mbps (with 256 channels per stream),
8.192 Mbps (with 128 channels per stream),
4.096 Mbps (with 64 channels per stream) or
2.048 Mbps (with 32 channels per stream).
The data rate is independently programmable for each output stream.
In Local 32 Mbps Mode, these pins output serial TDM data streams at a fixed
data rate of 32.768 Mbps (with 512 channels per stream).
Refer to the descriptions of the LORS and ODE pins for control of the output
HIGH or high impedance state.
Local Serial Output Streams 8 to 15 (5 V Tolerant Three-state Outputs
with Slew-Rate Control).
In Local Non-32 Mbps Mode, these pins output serial TDM data streams at a
data rate of:
16.384 Mbps (with 256 channels per stream),
8.192 Mbps (with 128 channels per stream),
4.096 Mbps (with 64 channels per stream) or
2.048 Mbps (with 32 channels per stream).
The data rate is independently programmable for each output stream.
These pins are unused when the Local 32 Mbps Mode is selected. Therefore,
the value output on these pins during Local 32 Mbps Mode (either
driven-HIGH or high impedance) is dependent on the configuration of the
LORS pin.
Refer to the descriptions of the LORS and ODE pins for control of the output
HIGH or high impedance state.
