SW2 fault management mode (MODE pin)

The SW2 selector is used to connect the MODE to AVCC or ground. When the jumper is set

to the upper position, the MODE pin is connected to ground and the corresponding fault

management is summarized in the first column of Table 4.

Otherwise, when SW2 is set to the “down” position, the MODE pin is connected to AVCC

and the corresponding fault management is summarized in the second column of Table 4.
