content of the W0R0 registers (see Figure 16). This method allows to change frequency
and duty cycle without glitch.
Note:
Figure 17. PWMU0 Interrupt System
The W0INVn bits that allow output inversion are on the W0MOD (W0 Counter Mode)
register (See Table 26.).

If the PWMU0 is off (W0R bit in W0CON not set), W0RnH and W0RnL contents are auto-
matically copied on the shadow registers SW0RnH and SW0RnLn and the contents of
W0FH and W0FL are automatically copied on the shadow registers SW0FH and SW0FL.
This allows to charge the correct comparison values for each PWM module as soon as
the PWMU0 timer/counter is turned on.
