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:
T1stpulse = TFICLK × 8 × OSHTWTH
Where TFICLK is the period of the system clock (FICLK) and OSHTWTH is the four control bits (value from 1 to 16)
Figure 12-285 shows the first and subsequent sustaining pulses.
