Hi all,

Has anyone tried supplying a clock for the STR9 from an external source? If so, what have the results been?

I am aware the oscillator takes around 3ms to start up.

Thanks in advance,

prw

Hi. I use 25MHz external clock signal connected to X1_CPU pin in my project. I haven't observed any problems. However, I have never performed any measurements regarding to startup delay...
