I made a circuit that transmit two set of numbers to another MCU circuit,but the circuit can't start by itself,it will start when I uses a probe fro the oscilloscope to test of the legs of the crystal,once the probe is remove,it can hold for few second and it die,I uses 16MHz crystal with two 22pF capacitor tie to ground,is the load capacitance of the crystal not suitable for the MCU?I try to search in the datasheet what crystal to use but I found nothing,it only show what model crystal it uses to test the MCU,I can't find the datasheet of the crystal
MCU used is PIC16F877A
