18.1.5
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 18-4:
TABLE 18-1:
TABLE 18-2:
18.1.6
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.
18.1.7
The PWM frequency is derived from the system clock
frequency (F
quency will result in changes to the PWM frequency.
Refer to
additional details.
18.1.8
Any Reset will force all ports to Input mode and the
PWM registers to their Reset states.
