24.3.3 Hysteresis
24.3.4 Input Selection
24.3.5 Interrupts and PRS Output
2010-09-06 - d0001_Rev1.00
In the voltage supply comparator, hysteresis can be enabled by setting HYSTEN in VCMP_CTRL. When
HYSTEN is set, the digital output will not toggle until the positive input voltage is at least 20mV above
or below the negative input voltage. This feature can be used to filter out uninteresting input fluctuations
around zero and only show changes that are big enough to breach the hysteresis threshold.
Figure 24.2. VCMP 20 mV Hysteresis Enabled
The positive comparator input is always connected to the scaled power supply input. The negative
comparator input is connected to the internal 1.25 V bandgap reference. The V
configured by setting the TRIGLEVEL field in VCMP_CTRL according to the following formula:
VCMP V
A low power reference mode can be enabled by setting the LPREF bit in VCMP_INPUTSEL. In this mode,
the power consumption in the reference buffer (V
The VCMP includes an edge triggered interrupt flag (EDGE in VCMP_IF). If either IRISE and/or IFALL in
VCMPn_CTRL is set, the EDGE interrupt flag will be set on rising and/or falling edge of the comparator
