Milliseconds specifies how long to output the frequency s. Freq1 specifies the first frequency in 1Hz units Hz.
Freq2 is optional and specifies a second frequency. The pin may be filtered by an RC circuit to achieve a clean sine-wave s.

High-Z speakers may be driven with a coupling cap and a filter cap. The default on and off times are ms and 50ms.
The pin may be filtered by an RC circuit to achieve a clean sine-waves. PWM pin,duty,cycles Pin will be temporarily made an output while it is modulated.
Duty is an 8-bit value which specifies the duty-cycle. When done, pin will be placed in input mode to allow the voltage to remain until another PWM is executed.
A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS. The resistor-cap junction will reflect the duty V during and after PWM.
RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’. The result will be written into variable.
For microptocessadores, to convert a potentiometer setting to a number: Adjusting the pot causes the returned value to go up or down.
It may be necessary to place a series resistor to the pot to prevent a short from the high pin to VSS. NAP x Enter low-power mode for a short period. The x values for NAP are as follows: Approximately 50ua average current will be consumed.
END is terminated only by a hardware reset.
STOP Execution is frozen, but low-power mode is not entered. Reset will end STOP.
