11.2.2
The read mode of the interface means that the
microcontroller reads data from the PCF8811. To do so the
microcontroller first has to send a command (the read
status command) and then the following byte is
transmitted in the opposite direction (using SDO) (see
Fig.21). After that, SCE is required to go HIGH before
a new command is sent.
The PCF8811 samples the SDATA data on the rising
SCLK edges, but shifts SDO data on the falling SCLK
edges. Thus the microcontroller is supposed to read SDO
data on rising SCLK edges.

After the read status command has been sent, the SDATA
line must be set to 3-state not later then the falling SCLK
edge of the last bit (see Fig.21).
The 8th read bit is shorter than the others because it is
terminated by the rising SCLK edge (see Fig.40). The last
rising SCLK edge sets SDO to 3-state after the delay
time t4.
The serial interface timing diagram is given in Chapter 19.
