Flowchart for interrupt function operation
Firstly, it is recommended to clear the register prior to enabling the interrupt
function. Use the SCPI command “
*CLS
” to clear the register.
Secondly, choose the trigger source (for example bit 301) using the SCPI
command “
SENS:DIG:INT:ENAB
ON,(@301)
”.
Then, enable the
Interrupt Operation Register
so that it will alert the
Status Byte
Register
whenever an interrupt has occured.
Finally, check the status in
Status Byte Register
with the SCPI command “
*STB?
”.
If bit 0 of STB returns “
1
”, it means that an interrupt has occurred. If bit 0 of STB
returns “
0
”, continue to check its status. The user may do something when an
interrupt has occured, for example output a signal from the DIO device.
