Property reference

	Properties
	Enable
	Connections
	Channel
PWM Channel selector
	Alt Pin Enable
Alternative Pin Enable (if available on target device)
	Port
	Configuration
	Period Register
Allows the user to change the number of counts for the whole PWM period. Note that all PWM channels based on the same timer will share the same period overflow. PIC/AVR Range: 0 - 255 16-bit PIC Range: 0 - 65535
	Prescaler Divide
Allows the user to change the number of program cycles per PWM cycle count. Note that all PWM channels based on the same timer will share the same prescaler.
	PWM Timer
Timer associated with PWM to drive the output. Warning - All PWM channels linked to the same timer will share the same period and prescaler settings.
	Clock Speed
	Period (uS)
	Frequency (KHz)
	Frequency (Hz)
	Master Divider
