NOTE The set-up time ts is defined as the minimum time that can elapse between a L ¡ H transition of the control input and the next L ¡ H clock pulse transition to ensure that the ÷P mode is obtained. The release time tr is defined as the minimum time that can elapse between a H ¡ L transition of the control input and the next L ¡ H clock pulse transition to ensure that the ÷(P +1) mode is obtain
