Hi, my problem is that I've got a peripheral device which is included in my system's memory space and the device want's to delay the transfer cycle of the ARM. Sometimes it can happen that the device needs 100ns and the other time it just needs 20ns. But I don't want to slow down the ARM to always 100ns :-( Does anyone have got a solution for my problem? Thx in advance!
