M0564
6.5 Analog Comparator Controller (ACMP)
6.5.1 Overview
M0564 contains two analog comparators. The comparator output is logic 1 when positive input is
greater than negative input; otherwise, the output is 0. Each comparator can be configured to
generate an interrupt when the comparator output state changes.
6.5.2
Features
 Analog input voltage range: 0 ~ V_DDA (voltage of AV_DD pin)
 Supports hysteresis function
 Supports wake-up function
 Selectable input sources of positive input and negative input
 ACMP0 supports
– 4 positive sources:
 ACMP0_P0, ACMP0_P1, ACMP0_P2, or ACMP0_P3
– 3 negative sources:
