16-BIT TIMER (Cont’d)
Figure 51. One Pulse Mode Timing Example
Figure 52. Pulse Width Modulation Mode Timing Example with 2 Output Compare Functions
Note: On timers with only one Output Compare register, a fixed frequency PWM signal can be generated
using the output compare and the counter overflow to define the pulse length.
