MaxV - Current Value

My customer is using MAX V CPLD. Part numbers are 5M1270ZF256C4N, 5M1270ZF324C5N. They have to interface 5V address and data lines of flash memory to these CPLDs.
I studied datasheet, it is saying that we can interface 5V signal to Bank-3 IO pins if we use series resister plus internal I/O clamp diodes being enabled. I could not find acceptable current limit for clamp diode from datasheet. So that I can calculate resister value.
Can you please provide max and nominal current limit value for internal IO clamp diode which can pass safely through it?

Regards

    Hi,

    there's a recommendation of 5 mA maximal clamping current for 100 % duty cycle in the multi-voltage chapter.

    Regards Frank
