EXAMPLE 2:
(Assumes that the T2CON and CCP1CON values may change during program execution. One SRAM location is used
for temporary storage of T2CON or CCP2CON.)

Call these routines to turn the PWM off or on and ensure a Zero output on RB3
when PWM is off.
PWMreset - Saves T2CON value in RAM location. IT IS THE RESPONSIBILITY OF THE USER TO SUPPLY
PWMrestart - Enable Timer2

RAM MEMORY SPACE TO SAVE THE T2CON VALUE.
Clears T2CON register Disabling Timer2 and clearing Timer2 Prescaler.
The TMR2 register is then filled with the CCPR1H value. This causes a Reset
or Zero value on RB3.
