power Stage x, xsel1 and xsel2 are LOW, the power stage x is controlled only via the SPI
control bit xON. If the selection bit xsel1 is HIGH and the control bit xON is also high, the
power stage x is controlled by the PWM1 pin (xsel2 and PWM2, respectively). The
behavior is shown in the pricipal schematic and truth table below. In terms of power
dissipation due to switching loss, a PWM frequency below 200 Hz is recommended.
