Hi I need to run a PIC16F84 on 4.194304 MHz (2^22 hz) for some precision timing, and since this clock speed is a multiple of 1024, it works extremely well with the Timer0 module on the PIC. Question is, would it hurt to run a 4Mhz PIC at this speed, or should I rather opt for a 10Mhz PIC? Regards, Werner Soekoe Information Systems Manager Free State Legislature werners@fsl.gov.za Tel.
