Abstract
A system including a processing core configured to generate a request signal to transfer data between a host device and a peripheral device. The processing core is in a low power state subsequent to generating the request signal. An interface module, separate from the processing core, is configured to transmit a sequence of commands from the host device to the peripheral device based on the request signal. The sequence of commands is transmitted to initiate the transfer of the data between the host device and the peripheral device. A comparator configured to compare expected responses of the peripheral device to the sequence of commands against responses received from the peripheral device to control the transfer of the data between the host device and the peripheral device without waking up the processing core from the low power state.
