Hi, i am having problems with the clock of the ARM 7026. I configure the PLLCON and POWCON like this: POWKEY1=0x01; POWCON=0x00; POWKEY2=0xF4; PLLKEY1=0xAA; PLLCON=0x00; PLLKEY2=0x55; but i don't get a speed of 45MHz. There is 1us between a set bit and a clear bit of gp port, so only 1MHz. And the C compiler generates only 3 assembly instructions for doing it. Can anyone help me how to increase the speed, and where's the problem? (in 'C' of course). I need up to 20MHz on an output pin. Thanks.
