18.12.2 Interrupt Sources
MMC2107 – Rev. 2.0
MOTOROLA
However, status flags must be cleared after an interrupt is serviced, in
to disable the interrupt request
In both polled and interrupt-driven operating modes, status flags must be
re-enabled after an event occurs. Flags are re-enabled by clearing
appropriate QASR bits in a particular sequence. The register must first
be read, then 0s must be written to the flags that are to be cleared. If a
new event occurs between the time that the register is read and the time
that it is written, the associated flag is not cleared.
The QADC includes four sources of interrupt requests, each of which is
separately enabled. Each time the result is written for the last conversion
command word (CCW) in a queue, the completion flag for the
corresponding queue is set, and when enabled, an interrupt request is
generated. In the same way, each time the result is written for a CCW
with the pause bit set, the queue pause flag is set, and when enabled,
an interrupt request is generated. Refer to
The pause and complete interrupts for queue 1 and queue 2 have
separate interrupt vector levels, so that each source can be separately
serviced.
