AD9510/PCB
Master Reset and Load Control Command Buttons
There are several command buttons, diagramed in Figure 31, which are located in the lower left-hand corner of the main interface
window. They serve several purposes:
•
The large red command button is a master reset, which resets the AD9510 to its default power-up state. This is an asynchronous
command that can be issued at any time. It automatically resets the part to the default power-up state and then reloads the interface
blocks to reflect the reset values.
•
The auto-update check box controls how the AD9510 is updated. When a new value is written to a given register, the AD9510 does
not use the new information until an update command is given. When the auto-update check box is selected, this update command
is automatically given when load is pressed.
•
The load all registers check box lets you select whether to load only the changed registers or to load the entire register map. If the
load all registers check box is cleared, then only the changed registers are loaded when load is pressed. Otherwise, all the registers are
loaded. This can be useful if you want to set a part up exactly the way it was before a hardware reset occurred; for example, if a power
supply was cutoff to the part.
•
The remaining three buttons are self-explanatory. The load button loads the current settings into the part, the read button reads the
current settings from the part, and the manual update button sends the update command to the part. If the auto-update check box is
selected, the manual update button does not need to be pressed after a load command.
