2.7 Interrupt Switches

The M3A-HS64 includes two push-button switches (NMI switch and IRQ1 switch) for the NMI and IRQ1 interrupt signals input
from the SH7264, and a push-button switch (TEST switch) for test signals.
The TEST switch is open to allow for connecting a desired pin. Set JP6 to use IRQ1 switch.
The figure below shows the interrupt switch block diagram. The table below lists the jumper setting (JP6).
