A few bods have mentioned that they are annoyed by the way in which a large number of micros divide down the external clock, resonator or crystal usually, and run instructions at that speed .... What are the reasons for people finding this so distasteful? I understand that clock division and PLL circuits can be noisey, but I get the feeling that this is not the only reason. regards, SW. ______________________________ Reply Separator _________________________________ Subject: Re: ATMEL Author: pic microcontroller discussion list at INTERNET Date: 08/07/98 12:02 It's a pity zilog hasn't seen the light. If the Z8 was flash, and didn't have the clock/8 "feature", then they'd rule the world!
