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.
When GCEN0 is set to ‘1’, channels 0 and 1 outputs are driven with gray counter.
