9.1.2
The read mode of the interface means that the
microcontroller reads data from the OM6208. To do so the
microcontroller first has to send a command, the read
status command, and then OM6208 will respond by
transmitting data on the SDO line. After that, SCE is
required to go HIGH (see Fig.14).
The OM6208 samples the SDATA data at rising SCLK
edges, but shifts SDO data at falling SCLK edges. Thus

the SDO data is available to be read by the microcontroller
at rising SCLK edges.
After the read status command has been sent, the SDATA
line must be set to 3-state (high-impedance) not later than
at the falling SCLK edge of the last bit (see Fig.14).
For the read data format, see Section 9.2.3; the serial
interface timing diagram is given in Chapter 15.
