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.
Could you please tell from where did you buy the ADUC7026? I've seen that Aanalog Devices don't send samples of this chip. Regards, Robert
