GPTIMER
The General Purpose Timer Unit provides a common prescaler and decrementing timer(s). The number of timers is configurable in the range 1 to 7.
The core is capable of asserting interrupts on timer underflow. The interrupt to use is configurable to be common for the whole unit or separate for each timer.
The estimated resource utilization of the GPTIMER is:
The following is a summary of the features:
- Interrupt generation on timer underflow
- Separate interrupts per timer or one common interrupt for all timers
- Configurable number of timers
- Configurable prescaler width
- Configurable timer width
- The last timer can optionally drive a watchdog output signal when expired
