IAP commands not working after PLL set

Hi

Im using a lpc1549 and trying to use the IAP commands (particularly the eeprom read/write). This seems to work at the base 12MHz frequency, until I set the PLL to be 72MHz and set the main system clock to be PLL. It doesn't matter if I use the IAP setPLL function of my own bit twidding function.  Then calling an IAP command results in a hardware error

 

Does this mean I can't use the commands if running at full speed? or is there something I need to do ?

 

Thanks for your help

Richard
