Timer with Eight Programmable Channels
- Three-channel and five-channel, 16-bit timer systems
-
Each channel programmable for
- Input capture, output compare or buffered pulse-width modulator (PWM)
- PWM can be edge-or center-aligned
- 16-bit free-running or up/down (CPWM) count operation
Extensive Serial Communications
