I\O Speed Problem

Siddharth Vaidya over 18 years ago

Hi,

I am using my LPC2364 at 75Mhz and i am getting maximum i|O frequency upto 13MHz only. Even if i toggle just one bit.

I want upto 16MHz minimum frequency of I\O. Can i do it with Thumb instructions or 13Mhz is the max??

Actualy VPBDIV is for LPC21xx. Sorry for that. Check bit PPCLKSEL1[3:2] for LPC23xx. When set as 01you get PCLK = CCLK . With default value (00) you get PCLK = CCLK/4
