8.13.4 Initializing the QADC for Interrupt Driven Operation
8-34
MOTOROLA
The following steps are required to ensure proper operation of QADC interrupts:
1. Assign the QADC a unique non-zero IARB value. The IARB field is located in
2. Set the interrupt request levels for queue 1 and queue 2 in the IRLQ1 and
3. Set the six high-order bits of the eight-bit IVB field in QADCINT. The QADC pro-
QADCMCR. The lowest priority IARB value is %0001, and the highest priority
IARB value is %1111.
IRLQ2 fields in QADCINT. Level %001 is the lowest priority interrupt request,
and level %111 is the highest priority request.
vides the two low-order vector bits to identify one of four QADC interrupt re-
quests. The vector number for each QADC interrupt source corresponds to a
specific vector in the exception vector table. Each vector in the exception vector
table points to the beginning address of an exception handler routine.
