is used when compatibility with 8-bit ADC designs are required. No interlocking between ADRH and ADRL
is present.
3.4 Monotonicity
The conversion process is monotonic and has no missing codes.
3.5 Interrupts
When the AIEN bit is set, the ADC module is capable of generating CPU interrupts after each ADC
conversion. A CPU interrupt is generated if the COCO bit is a 0. The COCO bit is not used as a
conversion complete flag when interrupts are enabled.
3.6 Low-Power Modes
The WAIT and STOP instruction can put the MCU in low power-consumption standby modes.
Freescale Semiconductor
Quantization error is affected when only the most significant eight bits are
used as a result. See
