Quiet Mode
During step 3 above, if the LOADA pulse is also strobed, the latch is configured to
connect the selected input to the ninth, auxiliary output.
Note that a QUIET mode is available as shown in Table 3-2. In QUIET mode, the outputs
are latched in a DC state with OUTX = 1 and OUTX = 0.
3.2.2 Stage Two: Configuring the Matrix
A CONFIGURE strobe is applied to transfer the contents of the LOAD latch into the
CONFIG latch. This action will cause the data flow through the GX9533 to be switched
to the new configuration. Refer to Figure 3-4 for detailed timing information.
Note that any single output can be asynchronously switched by having LOAD (or
LOADA if desired) held high while CONFIG is strobed.
