LCSTo0-3
C17, C16, B16, A16
Local Output Channel High Impedance Control (5V Tolerant Three-state
Outputs).
Active high output enable which may be used to control external buffering
individually for a set of local output streams on a per channel basis.
LCSTo0 is the output enable for LSTo[0,4,8,12,16,20,24,28],
LCSTo1 is the output enable for LSTo[1,5,9,13,17,21,25,29],
LCSTo2 is the output enable for LSTo[2,6,10,14,18,22,26,30],
LCSTo3 is the output enable for LSTo[3,7,11,15,19,23,27,31].
Refer to descriptions of the
LORS
and
ODE
pins for control of the output High or
High-Impedance state.
ODE
A12
Output Drive Enable (5V Tolerant, Internal pull-up).
An asynchronous input providing Output Enable control to the BSTo0- 31, LSTo0-
31, BCSTo0-3 and LCSTo0-3 outputs.
When LOW, the BSTo0-31 and LSTo0- 31 outputs are driven high or high
impedance (dependent on the
BORS
and
LORS
pin settings respectively) and the
outputs BCSTo0-3 and LCSTo0-3 are driven low.
When HIGH, the outputs BSTo0- 31, LSTo0-31, BCSTo0-3 and LCSTo0-3 are
enabled.
BORS
K2
Backplane Output Reset State (5V 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 in Backplane Connection Memory.
LORS
K19
Local Output Reset State (5V Tolerant, Internal pull-down).
When this input is LOW, the device will initialize with the LSTo0-31 outputs driven
high and the LCSTo0-3 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
LCSTo0-3.
When this input is HIGH, the device will initialize with the LSTo0-31 outputs at high
impedance and the LCSTo0-3 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 Local Connection Memory.
