The width of the first pulse can be programmed to any of 16 possible pulse width values. The width or period of the first pulse is given by:
Where TEPWMCLK is the period of the system clock (EPWMCLK) and OSHTWTH is the four control bits (value from 1 to 16)
Figure 7-223 shows the first and subsequent sustaining pulses and Table 7-183 gives the possible pulse width values for a EPWMCLK = 80 MHz.
