4.3 Crosspoint Switch Matrix Operation
The crosspoint switch matrix routes the serial digital input signals
(SDI[0:287]/SDI[0:287], EXT_PG0/EXT_PG0 or EXT_PG1/EXT_PG1) to one or more serial
digital outputs (SDO[0:287]/SDO[0:287], MON0/MON0 or MON1/MON1). The matrix is
configured on a per output basis. Each serial digital output can be configured to accept
a signal from one serial digital input. Multiple serial digital outputs can accept input
from the same serial digital input.
