Honored ContributorValue of pull up resistor
Hi everyone,
What is the value of the pull up resistor if enabled in MAX V 5M2210ZF256C4N CPLD. Thanks in advance :):)Forum Discussion

But then I would like to know a more specific value. Because termination resistance is vital in my application. Or else is there a pin impedance value..?

If you need a tightly tolerated pull-up resistor for some reason, place an external resistor.
