Field Descriptions
Interrupt 1
This field arms or disarms the Interrupt 1 pin. When it is armed, and the pin is
pulled low by an external device,
Tripped is displayed below the field until the
interrupt is re-armed.
Operating Considerations
The field can be queried directly in an IBASIC or HP-IB program, or it can be
monitored with the HP-IB status reporting system. This is done by reading bit 5 of
the status byte and then reading bit 13 of the Hardware 1 status register. The
Interrupt 1 pin can also be set as the HP-IB SRQ mask.
Once the interrupt has been tripped it must be re-armed. To do this, remove the
low on the Interrupt 1 pin and then set the
Interrupt 1 field to Disable and
then set it to
Arm.
Interrupts can be disabled and any external signals will have no effect on the
interrupt.
Both Interrupt 1 and Interrupt 2 are independent, and they can be used
simultaneously.

INTERFACE connector and bit 14 of the Hardware 1 status register.
