QADC64E Enhanced Mode Operation
configures the corresponding signal as an input. The software is responsible for ensuring that DDR bits are
not set to one on signals used for analog inputs. When the DDR bit is set to one and the signal is selected
for analog conversion, the voltage sampled is that of the output digital driver as influenced by the load.
There are two special cases to consider for the digital I/O port operation. When QACR0[EMUX] bit is set,
enabling external multiplexing, the data direction register settings are ignored for the bits corresponding
to PORTQA[2:0], which are the three multiplexed address output signals, MA[2:0]. The MA[2:0] signals
are forced to be digital outputs, regardless of the data direction setting, and the multiplexed address outputs
are driven. The data returned during a port data register read is the value of the multiplexed address latches
which drive MA[2:0], regardless of the data direction setting.
14.3.5
Control Register 0 defines whether external multiplexing is enabled, assigns external triggers to the
conversion queues and sets up the QCLK prescaler parameter field. All of the implemented control register
fields can be read or written but reserved fields read zero and writes have no effect. Typically, they are
written once when software initializes the QADC64E and are not changed afterwards.

Caution should be exercised when mixing digital and analog inputs. This
should be isolated as much as possible. Rise and fall times should be as large
as possible to minimize AC coupling effects.
