Direct/Indirect Write Mode
The MACOM EVM software has two modes of operation, and can be switched between them at any time by
clicking the “Direct Write” check-box located in the toolbar (see
Figure 2-4.
MACOM GUI Toolbar
Direct Write Mode
In this mode any changes made in the software are immediately written to the device without any further actions
necessary. When a direct-write occurs, the field will momentarily flash to indicate that the write is taking place. This
applies throughout the interface, except for the “Direct Register Access” control (see
), which still
requires that the “Write” button be clicked in order to commit a change.
Indirect Write Mode (Direct Write disabled)
In this mode, changes made in the software are not written to the device until “Write Changes” or “Write All” is
clicked. Any items that have been modified will appear in
color
to make it clear that these items have not been
written.This color may be altered by going to the “Log” tab and clicking on the color wheel at the bottom.
