Enhanced Queued Analog-to-Digital Converter (eQADC)MPC5566 Microcontroller Reference Manual, Rev. 219-108 Freescale Semiconductorvalues, they are added according to the RSD algorithm to create the 12-bit digital representation of theoriginal analog input. The bits are added in the following manner:19.4.9.2.3 RSD AdderThe array, s1 to s12, are the digital output of the RSD ADC with s1 being the MSB (most significant bit)and s12 being the LSB (least significant bit).Figure 19-63. RSD Adder19.5 Initialization and Application Information19.5.1 Multiple Queues Control Setup ExampleThis section provides an example of how to configure multiple user command queues. Table 19-56describes how each queue can be used for a different application. Also documented in this section aregeneral guidelines on how to initialize the on-chip ADCs and the external device, and how to configurethe command queues and the eQADC.Table 19-56.
