QADC64E Legacy Mode Operation
corresponding locations in the result word table as scratch pad RAM, remembering that only 10 bits are
implemented. The result alignment is only implemented for software read operations. Since write
operations are not the normal use for the result registers, only one write data format is supported, which is
right justified data.
13.4
This section describes the QADC64E analog subsystem, which includes the front-end analog multiplexer
and analog-to-digital converter.
13.4.1
The analog subsystem consists of the path from the input signals to the A/D converter block. Signals from
the queue control logic are fed to the multiplexer and state machine. The end of convert (EOC) signal and
the successive-approximation register (SAR) are the result of the conversion.

Analog Subsystem
Analog-to-Digital Converter Operation
Some write operations, like bit manipulation, may not operate as expected
because the hardware cannot access a true 16-bit value.
