 		 #137896 - PLL lock timing
Responding to: ???'s previous message
Table 14.3 in the datasheet of the C8051F120 shows some typical lock timing characteristics. They are nowhere near 2 seconds. More like 200 us.

         why a switch ? It will give you all kins of proble            01/01/70 00:00      
         Maybe use a jumper instead of a switch?            01/01/70 00:00      
            better, yes, as good as none no.            01/01/70 00:00      
            it's commonly used.            01/01/70 00:00
