Figure 15-8. Pwm Output Signal Timing - Sharp Blue Treak LH75400 User Manual

Timers
Figure 15-8 shows an example of PWM output signal timing. To support the timing shown
in this figure, the following values need to be programmed into the registers.
• CMP1 = 0x0005 → Period
• CMP0 = 0x0001 → Period
Timer 0 settings:
• CMP_CAP_CTRL[15] = 1 → PWM mode
• CMP_CAP_CTRL[14] = 1 → Counter Clear
• CMP_CAP_CTRL[13:12] = 01 → CMP1
• CMP_CAP_CTRL[11:10] = 10 → CMP0
