Enhanced Queued Analog-to-Digital Converter (eQADC)
19.1 Introduction
The enhanced queued analog-to-digital converter (eQADC) of the MPC5553/MPC5554 provides accurate
and fast conversions for a wide range of applications. The eQADC provides a parallel interface to two
on-chip analog-to-digital converters (ADCs), and a single master to single slave serial interface to an
off-chip external device. The two on-chip ADCs are architected to allow access to all the analog channels.
