Queued Analog-to-Digital Converter (QADC)
28.2
28.3
This subsection describes the two modes of operation in which the QADC does not perform conversions
in a regular fashion:
28.3.1
The QDBG bit in the module configuration register (QADCMCR) governs behavior of the QADC when
the CPU enters background debug mode. When QDBG is clear, the QADC operates normally and is
unaffected by CPU background debug mode. See
(QADCMCR).
When QDBG is set and the CPU enters background debug mode, the QADC finishes any conversion in
progress and then freezes. This is QADC debug mode. Depending on when debug mode is entered, the
three possible queue freeze scenarios are:
28-2
•
•
•
•
Debug mode
Stop mode
When a queue is not executing, the QADC freezes immediately.
When a queue is executing, the QADC completes the current conversion and then freezes.
