title  "PWMOut - Output a PWM Analog Voltage"
;
;  This Application simply Outputs an Analog Voltage by Driving a 
;   Resistor/Capacitor ("RC") Network with a PWM signal.  
;
;  The PWM runs at 20 kHz, with a Duty Cycle range from 0 to 100% 
;   Demonstrated.
;  This is an Actual PWM Duty Cycle Range of 0 to 50 Instructions/usecs
;
;  Hardware Notes:
;   This application runs on a 16F84 executing at 4 MHz
;   _MCLR is tied through a 4.7K Resistor to Vcc and PWRT is Enabled
;   A 10K Resistor/0.1 uF Capacitor Network is connected to RA0 to Show 
;    the PWM in Operation
