51.6.2.4 2-bit Gray Up/Down Counter for Stepper Motor
A pair of channels may provide a 2-bit gray count waveform on two outputs. Dead-time generator and other
downstream logic can be configured on these channels.
Up or Down Count mode can be configured on-the-fly by means of PWM_SMMR configuration registers.
