PWM RESOLUTION
The resolution determines the number of available duty
cycles for a given period. For example, a 10-bit resolution
will result in 1024 discrete duty cycles, whereas an 8-bit
resolution will result in 256 discrete duty cycles.
The maximum PWM resolution is 10 bits when PR2 is
255. The resolution is a function of the PR2 register
value as shown by Equation 11-4.
EQUATION 11-4:
PWM RESOLUTION
TABLE 11-4:
EXAMPLE PWM FREQUENCIES AND RESOLUTIONS AT 40 MHz
TABLE 11-5:
EXAMPLE PWM FREQUENCIES AND RESOLUTIONS (FOSC = 20 MHz)
TABLE 11-6:
EXAMPLE PWM FREQUENCIES AND RESOLUTIONS (FOSC = 8 MHz)
Note:
If the pulse width value is greater than the
period the assigned PWM pin(s) will
remain unchanged.
