Abstract
A low-power mode for interfaces, such as secure digital input/output (SDIO) interfaces, is described. The low-power mode provides significant power savings while allowing rapid resumption of data transfer on the interface. The SDIO low-power mode gates an SDIO clock and transitions the SDIO bus to a 1-bit mode. One line of the bus carries the 1-bit data while another line carries interrupts from an SDIO peripheral. Normal data transmission results in enabling the SDIO clock and setting the bus set to the 4-bit mode.
