Note 1: Nominal value at center point of current trim range (CTMUICON<15:10> = 000000).
2: Parameters are characterized but not tested in manufacturing. Measurements taken with the following
conditions:
• VREF+ = AVDD = 3.3V
• ADC module configured for conversion speed of 500 ksps
• All PMD bits are cleared (PMDx = 0)
• Executing a while(1) statement
• Device operating from the FRC with no PLL
3: The CTMU module is functional at VBORMIN < VDD < VDDMIN, but with degraded performance. Unless
otherwise stated, module functionality is tested, but not characterized.
