M0519
6.17 Analog Comparator (ACMP)
6.17.1 Overview
The NuMicro^® M0519 Series contains three comparators. 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 cause an interrupt when the comparator output value changes.

6.17.2 Features
 Analog input voltage range: 0~ AV_DD
 Supports hysteresis function
 Supports wake-up function
 Supports comparator output inverse function
 Supports the comparator output can be the brake source for EPWM function
 ACMP0 supports
 2 positive sources: ACMP0_P and OP0_O
 2 negative sources: ACMP0_N and Internal band-gap voltage (V_BG)
 ACMP1 supports
 2 positive sources: ACMP1_P and OP1_O
 2 negative sources: ACMP1_N and Internal band-gap voltage (V_BG)
 ACMP2 supports
 1 positive sources: ACMP2_P
 2 negative sources: ACMP2_N and Internal band-gap voltage (V_BG)
 Shares one ACMP interrupt vector for all comparators
