Hi
I am using one of your AT91EB40A boards. As you know this has AT91R40008 and flash memory AT49bv1614. The data hold time after rising edge of the write signal (EBI 18 parameter from the electrical spec) for the at91r40008 is a minimum of 2.2ns, however the flash device requires a data hold time of 10ns minimum.

Could you provide an explanation as to why this works.
