Maximum ATD conversion clock frequency is 2 MHz. The max bus clock frequency is computed from the max ATD conversion
clock frequency times the indicated prescaler setting; i.e., for a PRS of 0, max bus clock = 2 (max ATD conversion clock
frequency) × 2 (Factor) = 4 MHz.
Use these settings if the maximum desired ATD conversion clock frequency is 1 MHz. The max bus clock frequency is
computed from the max ATD conversion clock frequency times the indicated prescaler setting; i.e., for a PRS of 0, max bus
clock = 1 (max ATD conversion clock frequency) × 2 (Factor) = 2 MHz.
Minimum ATD conversion clock frequency is 500 kHz. The min bus clock frequency is computed from the min ATD conversion
clock frequency times the indicated prescaler setting; i.e., for a PRS of 1, min bus clock = 0.5 (min ATD conversion clock
frequency) × 2 (Factor) = 1 MHz.
