19.1.5
The resolution determines the number of available duty
cycles for a given period. For example, a 10-bit resolu-
tion 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 19-4:
TABLE 19-1:
TABLE 19-2:
19.1.6
In Sleep mode, the TMR2 register will not increment
and the state of the module will not change. If the
PWMx pin is driving a value, it will continue to drive that
value. When the device wakes up, TMR2 will continue
from its previous state.
19.1.7
The PWM frequency is derived from the system clock
frequency (F
quency will result in changes to the PWM frequency.
Refer to Section 5.0 “Oscillator Module” for addi-
tional details.
19.1.8
Any Reset will force all ports to Input mode and the
PWM registers to their Reset states.
