SPCLR Command
Use the SPCLR command to flush the input and output buffers for SPI simulation. This
resets the buffers and clears out all values. Notice that if the SPI is currently shifting a
value, this command does not prevent the SPI from finishing the transfer. See SPDI
command and SPDO command for accessing the input and output buffers of the SPI
interface.
Syntax
>SPCLR
Example
>SPCLR
Clear input and output buffer for SPI simulation
SPDI Command
The SPDI command allows the user to input data into the SPI. If a data parameter is given,
the value is placed into the next slot in the SPI input buffer. Otherwise, if no parameter is
given, a window is displayed with the input buffer values. Input values can be entered
while the window is open. An arrow points to the next input value to the SPI. The
maximum number of input values is 256 bytes.
Syntax
>SPDI [<n>]
Where:
<n> The value to be entered into the next location in the input buffer
Example
>SPDI $55
Set the next input value to the SPI to $55
>SPDI
Pull up the data window with all the input values.
