Freescale Semiconductor
NOTE:
Finally, 8-bit truncation mode will place the eight MSBs in ADC data
register low (ADRL). The two LSBs are dropped. This mode of operation
is used when compatibility with 8-bit ADC designs are required. No
interlocking between ADRH and ADRL is present.
Quantization error is affected when only the most significant eight bits
are used as a result. See
The conversion process is monotonic and has no missing codes.
