Figure 13-2. Comparator Control/Status Register (CMPCSR)
This bit is implemented in two ways: as a real-time comparator output
or as a latched interrupt source. The state of CM3IE determines which
implementation is selected.
CM3IE = 0 (nonlatched mode) — This status bit is cleared only by two
means:
CM3IE = 1 (latched mode) — This latched status bit is set when the
voltage at CMP3+ (PD0) is larger than that of CMP3– (internal voltage
reference ~ 2 V
This status bit is set when the voltage at CMP12+ is larger than that
of CMP2–, otherwise, it is cleared. Reset clears this bit because the
comparator is disabled.
This status bit is set when the voltage at CMP12+ is larger than that
of CMP1–, otherwise, it is cleared. Reset clears this bit because the
comparator is disabled.
