How to set up a system clock with 32MHz?

Latest Updated:03/26/2009

Question:

Please advise me how to set up a system clock. For instance, how can I set it up at 32MHz?

Answer:

It is suggested to set up PLL at x2 of input clock 16MHz for initial starting up. PLL is initially set up at x1after reset. All of setting of SCKCR register is for oesillator frequency.

For instance, if setting up bit 10 ~ 8 of SCKCR register at "010", system clock is same as oscillator freqeuncy.
