4.13 Interrupt Switches

The M3A-HS64G02 includes two push-button switches (IRQ2 switch and IRQ3 switch) for the IRQ2, and IRQ3 interrupt signals
input from the SH7264.
Set JP8, and JP9 on the M3A-HS64, JP1, and JP2 on the M3A-HS64G02 to use these switches.
The figure below shows the interrupt switch block diagram. Table 4.13.1 lists the jumpers setting (JP8, and JP9 on the
M3A-HS64). Table 4.13.2 lists the jumpers setting (JP1, and JP2).
