jeroen3 0:d0306c0cbee6 3 * @brief Small driver to user CT32B0 for PWM
jeroen3 0:d0306c0cbee6 4 *
jeroen3 0:d0306c0cbee6 5 * @author Jeroen Lodder
jeroen3 0:d0306c0cbee6 6 * @date Oktober 2013
jeroen3 0:d0306c0cbee6 7 *
jeroen3 0:d0306c0cbee6 8 * @note Since only one timer is used to supply 4 PWM channels
jeroen3 0:d0306c0cbee6 9 * a problem occurs because CT32B0 only support 3 PWM channels.
jeroen3 0:d0306c0cbee6 10 *
jeroen3 0:d0306c0cbee6 11 * Since this software is designed for a H-Bridge implementation
jeroen3 0:d0306c0cbee6 12 * only 2 of 4 PWM channels are required to be active simultaneously.
jeroen3 0:d0306c0cbee6 13 *
jeroen3 0:d0306c0cbee6 14 * This is where the stage variable comes in:
jeroen3 0:d0306c0cbee6 15 * Stage 0: PWM enabled on MAT 0, MAT 1 and MAT 2.
jeroen3 0:d0306c0cbee6 16 * Stage 1: PWM enabled on MAT 0, MAT 1 and MAT 3.
jeroen3 0:d0306c0cbee6 17 * Unused MAT outputs will be pullled down.
