18.12.1 Interrupt Operation
Technical Data
500
The four interrupt lines are outputs of the module and have no priority or
arbitration within the module.
QADC inputs can be monitored by polling or by using interrupts. When
interrupts are not needed, software can disable the pause and
completion interrupts and monitor the completion flag and the pause flag
for each queue in the status register (QASR). In other words, flag bits
can be polled to determine when new results are available.
Table 18-18
correspond to queue 1 and queue 2 activity.
If interrupts are enabled for an event, the QADC requests interrupt
service when the event occurs. Using interrupts does not require
continuously polling the status flags to see if an event has taken place.
