Read Operation
A read operation is initiated by the host controller and consists of two bytes. The first byte contains the address specified by the host
controller and has a “0” as its MSB to indicate data direction. The second byte contains the data which is outputted by the sensor. The
communication is synchronized by SCLK. SDIO is changed on the falling edges of SCLK and is read on every rising edge of SCLK. The host
controller must release SDIO bus and handover the control of SDIO bus to the sensor on the falling edge of last address bit.
