Queue completion flag. Indicates that a queue scan has been completed. CF[1:2] is
set by the QADC when the input channel sample requested by the last CCW in the
queue is converted, and the result is stored in the result table.
When CFn is set and queue completion interrupts are enabled (QACRn[CIEn] = 1),
the QADC requests an interrupt. The interrupt request is cleared when a 0 is written
to the CF1 bit after it has been read as a 1. Once set, CF1 can be cleared only by a
reset or by writing a 0 to it.
CF[1:2] is updated by the QADC regardless of whether the corresponding interrupt is
enabled. This allows polled recognition of the queue scan completion.
Queue pause flag. Indicates that a queue scan has reached a pause. PF[1:2] is set by
the QADC when the current queue 1 CCW has the pause bit set, the selected input
channel has been converted, and the result has been stored in the result table.
When PFn is set and interrupts are enabled (QACRn[PIEn] = 1), the QADC requests
an interrupt. The interrupt request is cleared when a 0 is written to PFn, after it has
been read as a 1. Once set, PFn can be cleared only by reset or by writing a 0 to it.

Queue trigger overrun flag. Indicates that an unexpected trigger event has occurred
for queue 1. TOR[1:2] can be set only while the queue is in the active state.
Once set, TOR[1:2] is cleared only by a reset or by writing a 0 to it.
