6.2.7
The Read Display Status (RDDST) command returns a
32-bit display status information and can be accessed
when the PCF8833 is in normal Display mode (see
Section 6.2.11), in partial Display mode (see
Section 6.2.23) or in Sleep_IN mode; see Section 6.2.8.
The input and output data format is as follows: After the
command byte 09H is sent, the read starts with one
dummy clock cycle followed by the 4 status bytes (see
Fig.48).

When less than 33 read clock cycles are sent in Serial
mode the status read must be interrupted by a hardware
reset or a rising edge of SCE.
The definition of the display status bits is given in Table 11.
