Figure 3-6 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.
