The pin can also be used as a remote ON/OFF control input.
Table 2 shows several different ways of using this pin. See
Figure 7 for a description of the functions where the horizontal
axis (left hand side) represents the EXTERNAL CURRENT
LIMIT pin current. The meaning of the vertical axes varies
with function. For those that control the on/off states of the
