QADC64E Enhanced Mode Operation
The two queued analog-to-digital converter (QADC) modules on the MPC561/MPC563 devices are
10-bit, unipolar, successive approximation converters. The modules can be configured to operate in one of
two modes, legacy mode (for MPC555 compatibility) and enhanced mode. This chapter describes how the
module operates in enhanced mode. Refer to
information regarding the QADC64E functionality in legacy mode.
For this revision of the QADC, the name QADC64E implies the enhanced version of the QADC64
module, not just enhanced mode of operation. For simplicity, the names QADC and QADC64E may be
used interchangeably throughout this document.
