79 / 97 page NuMicro NUC230/240 Datasheet Dec. 30, 2014 Page 79 of 97 Revision 1.01 Up to 1 MSPS conversion rate (chip working at 5V) Three operating modes - Single mode: A/D conversion is performed one time on a specified channel - Single-cycle scan mode: A/D conversion is performed one cycle on all specified channels with the sequence from the smallest numbered channel to the largest numbered channel - Continuous scan mode: A/D converter continuously performs Single-cycle scan mode until software stops A/D conversion An A/D conversion can be started by: - Writing 1 to ADST bit (ADCR[11])through software - PWM Center-aligned trigger - External pin STADC Conversion results are held in data registers for each channel with valid and overrun indicators Supports two set digital comparators. The conversion result can be compared with specify value and user can select whether to generate an interrupt when conversion result matches the compare register setting Channel 7 supports 3 input sources: external analog voltage, internal Band-gap voltage, and internal temperature sensor output 6.22 Analog Comparator (ACMP) 6.22.1 Overview The NuMicro NUC230/240 series contains two comparators which can be used in a number of different configurations. The comparator output is logic 1 when positive input voltage is greater than negative input voltage; otherwise the output is logic 0. Each comparator can be configured to generate interrupt request when the comparator output value changes. The block diagram is shown in 錯誤! 找不到參照來源。. 6.22.2 Features Analog input voltage range: 0~ VDDA (Voltage of AVDD pin) Supports Hysteresis function Optional internal reference voltage source for each comparator negative input |
