I want to run a PIC from a 38 kHz crystal. The data sheet for the 16F84 states that for low frequency crystals, it may be necessary to insert a series resistor.
Does anyone know how to determine the value of this resistor? The one I intend to use has a 1 uW max drive level and an ESR of 35 k Ohm.
So do I assume that the drive level is V^2 * 35 k ?
