Overview of the AFE5832 EVM GUI Features
2. The Deferred update mode allows the user to change the values of any number of bits or fields within
the registers, but these changes will not be written to the device instantly. Unless the changes are
implemented, data cannot be read from the registers either.
When a user changes the contents of a register in
Deferred mode, the GUI will turn the changed
register font a blue color. These blue-font registers indicate that a change has been made but not yet
implemented.
Within the
Deferred update mode, there exist options in the top left-hand corner of the GUI for deciding
how the changes should be implemented (shown in Figure 57 ): (a) Read Selected data, (b) Write
Selected data, and (c) Write Modified data, or (d) Read All data.
1. Read Selected : Clicking this option in the top left-hand corner displays the value contained in the
register in the Read Data field in the lower right-hand corner of the GUI. In the same area of the
GUI, the Address field will display the address of the selected register, and the Value field will
display the value contained in that register as shown in Figure 57 .
2. Write Selected : This option indicates that only the values in a selected register is written to the
device. In order to select a particular register to write to, click on any register under Register Name
and then choose to write to the selected register.
3. Write Modified : If the user has made changes to multiple registers in the register map, this option
allows the user to write the changes within all modified registers to the device. Once all changes
have been written, there will no longer be any blue-font registers , indicating that all the changes
have been implemented.
4. Read All : This option reads data from all the registers in the device regardless of whether they are
selected or not.
NOTE: If any number of registers contains modified values that are not yet written, none of the
Read options can be used. The user is prompted to either write the modified fields to the
device or discard the changes.
