Hi, how can I set PLL config to get max? the default is 300 Mhz (16/8/150) but I'd like to get 330 Mhz.

Thanks~

Hi Young,

You can use the PLL configuration tool available at

http://www.ti.com/lsds/ti/arm/hercules_arm_cortex_r_safety_microcontrollers/arm_cortex_r4/rm4_arm_cortex_r4/toolsw.page#add (http://www.ti.com/tool/fmzpll_calculator)

But when you configure the CPU clock to 330 MHz pls try to make sure you get the fHCLK <=150 MHz using the BUS1CNTRL divider configuration. So when GCLK=330MHz you can go with HCLK(max)=110MHz.
