Note 6-1: The quantization error (±1/2LSB) is excluded from the absolute accuracy.
Note 6-2: The conversion time refers to the interval from the time a conversion starting instruction is issued till the time
the complete digital value against the analog input value is loaded in the result register.
The conversion time is twice the normal value when one of the following conditions occurs:
• The first AD conversion is executed in the 12-bit AD conversion mode after a system reset.
• The first AD conversion is executed after the AD conversion mode is switched from 8-bit to 12-bit AD conversion
mode.
