Hello everyone,

I'm reading the AT91SAM7S64 microcontrolle, but I can not find
the value of each I/0 line embedded pull up resistor.
Could someone tell me this one?
Moreover, I don't understand the meaning of the Input Pull up current electrical parameter.
Could someone explain me it?

Many thanks in advance.
Best Regards,
BigChobin.

Hi,

typical pull-up value on I/Os is 100Kohms.
Ipullup data given in the datasheet can be used.
R=U/I....
