14 years agoIf I remember correctly the loopback feature means that for output registers you can read back the values in software. If you want to be able to write to registers and also read from other registers you'll probably want to go with enabling inputs and outputs instead of using the loopback feature. Also if you need to know when a value is being written or read make sure to enable the synchronization logic as well so that you'll have access to the read and write strobes from the template.
