CHARACTERISTICS.
Before using the QADC64, the software must initialize the prescaler with values that
put the QCLK within the specified range. Though most software applications initialize
the prescaler once and do not change it, write operations to the prescaler fields are
permitted.
QCLK
For software compatibility with earlier versions of QADC64, the defi-
nition of PSL, PSH, and PSA have been maintained. However, the
requirements on minimum time and minimum low time no longer
exist.
A change in the prescaler value while a conversion is in progress is
likely to corrupt the result from any conversion in progress. There-
fore, any prescaler write operation should be done only when both
queues are in the disabled modes.
