CM2POR, IRQ2SEL: Bits in CMPA register
The above applies when:
• VCA27 bit in VCA2 register = 1 (comparator A2 circuit enabled)
• VW2C0 bit in VW2C register = 1 (comparator A2 interrupt enabled)
• CM2OE bit in CMPA register = 1 (output enabled)
• VCA24 bit in VCA2 register = 1 (LVCMP2 pin input voltage)
• COMPSEL bit in CMPA register = 1 (bits IRQ1SEL and IRQ2SEL enabled)
