PWM Mode — TnDPX = 1

Note: 1. Here TnDPX=1 – Counter cleared by CCRA

2. A counter clear sets the PWM Period

3. The internal PWM function continues even when TnIO [1:0] = 00 or 01

4. The TnCCLR bit has no influence on PWM operation

Single Pulse Mode

To select this mode, bits TnM1 and TnM0 in the TMnC1 register should be set to 10 respectively

and also the TnIO1 and TnIO0 bits should be set to 11 respectively. The Single Pulse Output Mode,

as the name suggests, will generate a single shot pulse on the TM output pin.

The trigger for the pulse output leading edge is a low to high transition of the TnON bit, which can

be implemented using the application program. However in the Single Pulse Mode, the TnON bit

can also be made to automatically change from low to high using the external TCKn pin, which will

in turn initiate the Single Pulse output. When the TnON bit transitions to a high level, the counter

will start running and the pulse leading edge will be generated. The TnON bit should remain high

when the pulse is in its active state. The generated pulse trailing edge will be generated when the

TnON bit is cleared to zero, which can be implemented using the application program or when a

compare match occurs from Comparator A.
