The above applies when:
• VCA26 bit in VCA2 register = 1 (comparator A1 circuit enabled)
• VW1C0 bit in VW1C register = 1 (comparator A1 interrupt enabled)
• CM1OE bit in CMPA register = 1 (output enabled)
• VCA22 bit in VCA2 register = 1 (LVCMP1 pin input voltage)
• COMPSEL bit in CMPA register = 1 (bits IRQ1SEL and IRQ2SEL enabled)
