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

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.

Registers are updated with the internal

status at the rising edge of the internal

AMIS--30532 clock when CS = 1

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.
