Hello,

I use LPC1114 at 96MHz with external crystal at 12MHz :
LPC_SYSCON->MAINCLKSEL = 0x03;
LPC_SYSCON->MAINCLKUEN = 0;
LPC_SYSCON->MAINCLKUEN = 1;

LPC_SYSCON->SYSPLLCLKSEL = 0x01;// select external crystal input
LPC_SYSCON->SYSPLLCTRL = ((0<<5)| 0x07);// 96MHz
LPC_SYSCON->SYSPLLCLKUEN = 0;
LPC_SYSCON->SYSPLLCLKUEN = 1;

It's work fine, but in some case I have a problem Hardfault handler.
If I put 48MHz, I haven't the problem.

What do you think ?

The fastest LPC1114 runs is 50Mhz.
