SOPC - simple question

Thank you for your response!

I implemented my counter using PIO and it seems to work!

But now, I want to add an option to clear my counter and here I have a question: may I simply connect PIO output port to PIO input port of my counter? I did it but something is wrong, it doesn't want to change value to zero... I am not sure which address should be changed: base, end or the whole page?

Thanks in advance for your help,

Best regards,

Koza

PS. Part of my design file showing (I hope) the problem can be found here: www.twojekorki.republika.pl/clear.jpg

PS2. If someone plays with uclinux, my code was something like that:

# define READ_C (*(unsigned int *)0x10)

# define ZERO_ADD (*(unsigned int *)0x20)

//clear

ZERO_ADD = x0ffffffff;

ZERO_ADD = 0;

//read

int r = (unsigned int)READ_C;
