Socket address lines are normal.
Socket address lines A[25:4] are high-impedance.
-VCC_5 activated when card power is to be applied.
-VCC_3 activated when card power is to be applied.
Interrupts are passed to the IRQ[XX] pin as level-sensitive.
When an interrupt occurs, the IRQ[XX] pin is driven with the pulse train shown in Table 12 and
allows for interrupt sharing.
