I/O: Capital letters (I, O) represent the input/output direction in the initial settings.
OP: Selected by mask option ("–" means "no option provided.")
SFT: Switched by software ("–" means "no software switch provided" and "D" means default function.)
Note: The TEST terminal must be connected to the V
SS
power supply. Be sure to avoid applying other
conditions to the terminals during normal operation.
