J jyothigk New Member Aug 20, 2009 #1 Is there any problem if I set BOR=off for 18f4520? (osc=32MHz Internal R-C oscillator)

J jyothigk New Member Aug 20, 2009 #3 Thanks.... But is it necessary to set BOR voltage = 4.5V fot high Fosc such as 32MHz?
W Wp100 Well-Known Member Aug 21, 2009 #4 Hi, According to the datasheet the chip will do 32meg down to 4.2v Think setting the BORV0/1 to 00 , min 4.36v typ 4.59v max 4.82v, will then ensure it resets well before 4.2v is reached.
