SBAU260 April 2016
Under default operation, any changes to registers via the Register Controls area triggers an immediate write register command. By selecting the manual update option in the File > Options menu, this button is enabled. When this mode is enabled, changes to register controls do not trigger a register write. Instead, this button must be clicked to submit a manual register write. The write operation is only performed on the register selected in the register table.
NOTE
The register map table will update with the change in register map control. However, a write command in not sent until commanded by the user via this button. Selecting the Refresh/Sync button before issuing the manual write will sync the register map and controls to the current value of the device.
