Package
Backplane Output Reset State (5 V Tolerant, Internal pull-down).
When this input is LOW the device will initialize with the BSTo0-31 outputs
driven high, and the BCSTo0-3 outputs driven low. Following initialization,
the Backplane 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 BCSTo0-3.
When this input is HIGH, the device will initialize with the BSTo0-31
outputs at high impedance and the BCSTo0-3 outputs driven low.
Following initialization, the Backplane stream outputs may be set active or
high impedance using the ODE pin, or on a per-channel basis with the BE
bit of the Backplane Connection Memory.
Local Output Reset State (5 V Tolerant, 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 the LCSTo0-1 outputs.
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
of the Local Connection Memory.
No Connect.
No connection to be made.
