PIC16F72 in HS mode, with 16M quartz crystal can not start, MCU 5V power supply, the configuration word is: __CONFIG (3FBAh), the same as the 16.000MHz quartz crystal problem does not start, matching capacitor 10p, 12p, 20p, 30p, Crystal two feet and 120K, 300K, 1M resistors have tried, still can not vibration, what is the problem with the master?
