16-BIT TIMER (Cont’d)
Figure 52. One Pulse Mode Timing Example
Figure 53. 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.
Note: OC1R = 2ED0h, OC2R = 34E2, OLVL1 = 0, OLVL2 = 1
Note: IEDG1 = 1, OC1R = 2ED0h, OLVL1 = 0, OLVL2 = 1
