The J25.1 and J25.2 pins are configurable through the J44 header. Refer to Table 4-
17, for a description of the possible configurations. 

The XL and XH signals are multiplexed with NEXUS signals. Due to that, 0 ohm 
resistors (R160 and R162) are inserted between these signals and I/O signals. There 
are not mounted by default. It means NEXUS signals are functional. Just mount these 
resistors to activate XL and XH signals. 

The differential measures and comparator detections are multiplexed. Due to that, 0 
ohm resistors (R157, R158, R159 and R161) are inserted. As there are mounted by 
default, differential measures and comparator detections are accessible. 

None.
