Note 7-1: The quantization error (
±1/2LSB) must be excluded from the absolute accuracy. The absolute accuracy must
be measured in the microcontroller's state in which no I/O operations occur at the pins adjacent to the analog
input channel.
Note 7-2: The conversion time refers to the period from the time an instruction for starting a conversion process till the
time the conversion results register(s) are loaded with a complete digital conversion value corresponding to
the analog input value.
The conversion time is 2 times the normal-time conversion time when:
The first AD conversion is performed in the 12-bit AD conversion mode after a system reset.
The first AD conversion is performed after the AD conversion mode is switched from 8-bit to 12-bit
conversion mode.
