4.4. Default slave

The default slave is used to respond to transfers that are made to undefined regions of memory, where no AHB system slaves are mapped. A zero wait OKAY response is made to IDLE or BUSY transfers, with an ERROR response being generated if a NONSEQUENTIAL or SEQUENTIAL transfer is performed. Figure 4.16 shows the default slave module interface diagram.
