6.20 Pulse Width Modulator (PWM)
www.ti.com
The 3 DM6435 Pulse Width Modulator (PWM) peripherals support the following features:
• Period counter
• First-phase duration counter
• Repeat count for one-shot operation
• Configurable to operate in either one-shot or continuous mode
• Buffered period and first-phase duration registers
• One-shot operation triggerable by hardware events with programmable edge transitions. (low-to-high or
high-to-low).
• One-shot operation generates N+1 periods of waveform, N being the repeat count register value
• Emulation support
The register memory maps for PWM0/1/2 are shown in Table 6-87, Table 6-88, and Table 6-89.
