Examples of Combined READ and WRITE
Operations
In the following examples successive READ and WRITE
operations are combined. In Figure 22 the Master first reads
the status from Register at ADDR4 and at ADDR5 followed
Registers are updated with the internal
status at the rising edge of the internal
by writing a control byte in Control Register at ADDR2.
Note that during the write command the old data of the
pointed register is returned at the moment the new data is
shifted in.

Figure 22. 2 Successive READ Commands Followed by a WRITE Command
After the write operation the Master could initiate a read
back command in order to verify the data correctly written
as illustrated in Figure 23. During reception of the READ
command the old data is returned for a second time. Only
after receiving the READ command the new data is
transmitted. This rule also applies when the master device
wants to initiate an SPI transfer to read the Status Registers.
Because the internal system clock updates the Status
Registers only when CS line is high, the first read out byte
might represent old status information.
