system clock

hi im using a C8051 target board. i would like to know how can u set the system clcok frequency to 12MHZ?

The RTC?

Is it internally clocked? Normally, to set a chip to a specific frequency you'd need a specific crystal.

Also, this is NOT a C question, but should have been put into Tech Board.

Or the PIT?

The easiest way is to use Silabs Configuration Wizard to compute the proper values for the OSC.

Get a 12MHz crystal.

Or a slower crystal and use a phase locked loop to multiply the frequency, but that doesn't make sense at 12MHz (usually used for high frequencies because high frequency crystals are expensive/non-existent).

And what does this have to do with C?

Is there an echo in here?

Totally. I really should start reading replies before replying .
