(580h to 5FFh). These registers can be used as general purpose memory for the application (SLP) software and/or for serial communication data exchange. If the iMAC Controller’s serial communication protocol is set to Ampcontrol IP2, the General Buffer registers are the only addresses that are able to be accessed using this protocol. Application (SLP) software must move all data that is required to be exchanged using IP or IP2 protocols into these registers to enable access. -
