To read the values of a register, click the READ button. The value is read from the device and is displayed on a
label near the READ button. It is also displayed in the log window.
To write the bit values individually, click the desired bit. The corresponding bit button color changes. The value
is updated in the log window. Click the WRITE button to write the register. To write the values through a text box
near the WRITE button, enter the appropriate write value. Then click the WRITE button to write the register.
When registers have been selected, global commands can also be used:
• WRITE: Writes data to all the selected register at once.
• READ: Reads data back from the selected register at once.
• RESET: Resets all the input text boxes to 0x00. Write bits are set to 0. Change register bit buttons are set to
the default setting.
The value can also be written by selecting the Edit option near the WRITE button. Bits and corresponding
values are displayed in a pop window as shown in
Figure
36. Select the options of all write bits, close the input
dialog box, and click the WRITE button. Selected input combinations are written to the register.
