Hello,

I am building a project with a 16F84 and thought it would be a good idea to
incorporate a brownout circuit to reset the part in the event of a
brownout.  I want to use the circuit featured in the spec sheet for the
16C84 with a zener diode and a PNP transistor and a few resistors.  I have
a lot of BC328 sitting about so I thought that I would use a few.  Trouble
is that the circuit does not work for me.  Vdd is 5 volts I am using a 3.3V
zener.  I thought that the transistor would trigger when Vdd got to 4V, but
/MCLR does not go low till Vdd is approx 2V.  Has anyone had success with
this circuit and point me in the right direction.

Cheers
JD
