Notes:
Thanks to AMPCMP0 configuration bit, Comparator 0 positive input can be connected to
Amplifier O output. In that case, the clock of comparator 0 is twice the amplifier 0 clock.
“Amplifier 0 Control and Status register – AMP0CSR” on page 254.
Thanks to AMPCMP1 configuration bit, Comparator 1 positive input can be connected to
Amplifier 1 output. In that case, the clock of comparator 1 is twice the amplifier 1 clock.
“Amplifier 1 Control and Status register – AMP1CSR” on page 255.
Thanks to AMPCMP2 configuration bit, Comparator 2 positive input can be connected to
Amplifier 2 output. In that case, the clock of comparator 2 is twice the amplifier 2 clock.
