Description
These bits contain the four LSBs of the 12-bit t
bits of Register 0x49, which contains the eight MSBs of the t
5 ns resolution. The entire switching period is divided into 40 ns time steps. If the t_rise and
t_fall of a PWM edge occur within the same 40 ns time step, the PWM output is 0 V. If the t_rise
and t_fall occur in different 40 ns time steps, the PWM output is set to the programmed value.
The absolute maximum pulse width is t
1 = PWM modulation acts on the t
0 = no PWM modulation of the t
1 = negative sign. Increase of PWM modulation moves t
0 = positive sign. Increase of PWM modulation moves t
Reserved.
If this bit is set to 1, the OUTC rising edge is selected as the start of the integration period for
volt-second balance.

Description
This register contains the eight MSBs of the 12-bit t
top four bits of Register 0x4E, which contains the four LSBs of the t
to 5 ns resolution. The entire switching period is divided into 40 ns time steps. If the t_rise and
t_fall of a PWM edge occur within the same 40 ns time step, the PWM output is 0 V. If the t_rise
and t_fall occur in different 40 ns time steps, the PWM output is set to the programmed value.
