Note 1: Nominal value at center point of current trim range (CTMUICON<15:10> = 000000).
2: Parameters are characterized but not tested in manufacturing.
3: Measurements taken with the following conditions:
•VREF+ = AVDD = 3.3V
• ADC configured for 10-bit mode
• ADC module configured for conversion speed of 500 ksps
• All PMDx bits are cleared (PMDx = 0)
• Executing a while(1) statement
• Device operating from the FRC with no PLL
