This would mean that as long as the write cycle is still ongoing, a read command (to any address, or more precisely, to the LastWriteAddress + 1) will not be acknowledged, and this behavior can be interpreted as "busy"! This way, a fixed (and unnecessarily long) delay could be avoided. Regards, bfwolf.
