Timer_3 with 16 bits each. They can be used for D/A conversion, to control servo motors in pattern

making and to output audio frequencies. A pulse length modulated signal has a period of N so called

"Ticks". The duration of one tick is the time base. If the output value of a PLM port is set to X then

the port will hold high level for X ticks of one period and will then for the balance of the period drop to

low level. For programming of the PLM channels see Timer.

The PLM channels for Timer_0, Timer_1 and Timer_3 have independent time base and period length.

In applications for pulse width modulated digital to analog conversion the time base and period length

are set once and then only the output value is varied. According to their electrical properties the PLM

ports are digital ports. Please observe the technical boundary conditions for digital ports (max. cur-

rent).
