Freescale Semiconductor
The channel field is programmed for channel 63 to indicate the end of the queue. Channels 60 to 62 are
special internal channels. When one of the special channels is selected, the sampling amplifier is not used.
The value of VRL, VRH, or (VRH - VRL)/2 is placed directly onto the converter. Also for the internal
special channels, programming any input sample time other than two has no benefit except to lengthen the
overall conversion time.
13.3.10 Result Word Table
The result word table is a RAM, 64 words long and 10 bits wide. An entry is written by the QADC64E
after completing an analog conversion specified by the corresponding CCW table entry. Software can read
