QADC64E Enhanced Mode Operation
The QADC64E conditionally generates interrupts to the bus master via the IMB3 IRQ signals. When the
QADC64E sets a status bit assigned to generate an interrupt, the QADC64E drives the IRQ bus. The value
driven onto IRQ[7:0] represents the interrupt level assigned to the interrupt source. Under the control of
ILBS, each interrupt request level is driven during the time multiplexed bus during one of four different
time slots, with eight levels communicated per time slot. No hardware priority is assigned to interrupts.
Furthermore, if more than one source on a module requests an interrupt at the same level, the system
software must assign a priority to each source requesting at that level.
levels on IRQ with ILBS. Refer to
information.

QADC64E ports A and B are accessed through two 8-bit port data registers, PORTQA and PORTQB.

Queue 1 Interrupt Request Level. The IRL1 field establishes the queue 1 interrupt request level.
The 00000 state provides a level 0 interrupt while 11111 provides a level 31 interrupt. All
interrupts are presented on the IMB3. Interrupt level priority software determines which level has
the highest priority request.
Queue 2 Interrupt Request Level. The IRL2 field establishes the queue 2 interrupt request level.
The 00000 state provides a level 0 interrupt while 11111 provides a level 31 interrupt. All
interrupts are presented on the IMB3. Interrupt level priority software determines which level has
the highest priority request.
