NOTES:
(1) If Pin14 to VDD, use CUVLO=.1uF and omit D1,R2
(2) If Pin14 to VSS, use CUVLO=.22uF and omit C1,D1,R2
(3) If power supply rise time < 80msec (Figure 11), connect pin 14 to VSS, use CUVLO=.22uF, and omit C1,D1,R2.
(4) If Figure 13 circuit is used. Connect pin 14 to VDD. Use CUVLO=0.22uF and R1=0.
(5) Set RLS1, RLS2 for LNLED low above 85% of min operating voltage
