HIGH-END TIMER (HET) TIMINGS
Minimum PWM output pulse width:
This is equal to one high resolution clock period (HRP). The HRP is defined by the 6-bit high resolution prescale
factor (hr), which is user defined, giving prescale factors of 1 to 64 with a linear increment of codes.
Minimum input pulses we can capture:
The input pulse width must be greater or equal to the low resolution clock period (LRP), i.e., the HET loop (the
HET program must fit within the LRP). The LRP is defined by the 3-bit loop-resolution prescale factor (lr), which
is user defined, with a power of 2 increment of codes. That is, the value of lr can be 1, 2, 4, 8, 16, or 32.

Therefore, the minimum PWM output pulse width = HRP(min) = hr(min)/SYSCLK = 1/SYSCLK
For example, for a SYSCLK of 30 MHz, the minimum PWM output pulse width = 1/30 = 33.33ns
Therefore, the minimum input pulse width = LRP(min) = hr(min) * lr(min)/SYSCLK = 1 * 1/SYSCLK
For example, with a SYSCLK of 30 MHz, the minimum input pulse width = 1 * 1/30 = 33.33 ns
NOTE:
Once the input pulse width is greater than LRP, the resolution of the measurement is
still HRP. (That is, the captured value gives the number of HRP clocks inside the
pulse.)
Abbreviations:
hr = HET high resolution divide rate = 1, 2, 3,...63, 64
lr = HET low resolution divide rate = 1, 2, 4, 8, 16, 32
High resolution clock period = HRP = hr/SYSCLK
Loop resolution clock period = LRP = hr*lr/SYSCLK
