address. You will then know the starting address , and (from the
…NRAM:CRE < size> command) the length of the NRAM segment.
Example: Allocating an NRAM segment and locating it. This example shows
how to allocate a small 128 byte NRAM segment. In addition, it shows how to
determine the starting address of that segment.
define variables
10 REAL Addr,Size
128 byte NRAM segment
20 OUTPUT 70900;"DIAG:NRAM:CRE 128"
reset the system
30 OUTPUT 70900;"DIAG:BOOT"
allow time for reset to begin
40 WAIT 5
wait for self-test to complete
50 ON TIMEOUT 7,.1 GOTO Complete
60 Complete:B= SPOLL(70900)
query starting addr
70 OUTPUT 70900;"DIAG:NRAM:ADDR?"
enter starting addr
80 ENTER 70900;Addr
print it
