For different applications, users maybe need more than 8-bit resolution but less than 12-bit ADC converter. To process
the ADB and ADR data can make the job well. First, the AD resolution must be set 12-bit mode and then to execute
ADC converter routine. Then delete the LSB of ADC data and get the new resolution result. The table is as following.
