- NMI interrupt generation (with the jumper installed on pins 5-6 of the XP25 connector). With such
a configuration, the PFO# signal is switched to the IOCHK# line of the ISA bus.
See also paragraph 4.3.20 Configuration jumpers, paragraph 4.3.19 GPIO ports.
The PFO# signal is described in more detail in paragraph 4.3.18 Module power supply voltage
supervisor.
Figure 4.12 shows the implementation diagram of the opto-isolated reset/shutdown.

The external reset/interrupt circuit is connected to the XP19 connector. The location of the first pin
of this connector on the module is shown in Figure 4.13.
The module has a JST B 2B-PH-KL connector.
