Figure 11.46 SPI IN Buffer Display
SPI data output buffer simulation allows the user to gain access to the past 256 SPI data
values transmitted out of the module. To bring up the SPI OUT buffer dialog box, use the
SPDO command.
Figure 11.47 SPI OUT Buffer Display
At any point, SPCLR command can flush the input as well as output SPI buffers.
After the SPI simulated input is received, the first queued value is passed from the data
buffer into the SPI data register. It can be observed in the Memory Window by displaying
the memory location corresponding to the SPI data register.
Figure 11.48 Memory Component Window
The user can also observe different SPI flags in the Memory window. If the module is run
in the Flag Polling mode, poll the flag corresponding to the expected SPI event. If the SPI
