Hello,

In LPC17xx User manual (Section 4.10) it has been stated that :

"For system test and development purposes, any one of several internal clocks may be
brought out on the CLKOUT function available on the P1.27 pin, as shown in Figure 12."

Is there any problem if the CLKOUT function remains permanently ON to feed other parts as system clock ? I mean why manual has emphasized  "For system test and development purposes" ?
Should I reconsider using CLKOUT @48MHZ as system clock ?

Sincerely,
Tech19
