The output level of COMP3 and COMP2 are used to generate the master PWM[0]. The
SYNCR[1] and SYNCR[2] inputs are triggered respectively on the rising and falling edge of
the PWM[0]. These trigger signals are sent to interleaving blocks which generate the phase
shifted (120º/180º and 240º) ON/OFF signals for the other channels.
The SET[1], SET[2], RESET[1] and RESET[2] (pins: 4, 5, 8, 16) signals must be connected
to external devices (for example two flip-flops) in order to obtain the driving signals PWM1
and PWM2.
The ENABLE input (pin 18) performs a protection function. The connection to the CLOCK
signal (pin 2 at switching frequency) prevents undesired commutation of the PWM[0] and
consequently on the other channels.

Programming section
Device programming is done by using a PC with dedicated loader software (STNRG
LOADER), an FTDI cable and an adapter board (see Figure 8).
