11. 16-bit PPG Timer
This module can output a pulse synchronized with an external trigger or a software trigger. In addition, the cycle
and duty ratio of the output pulse can be changed as desired by overwriting the two 16-bit register values.
PWM function:
Synchronizes pulse with trigger, and permits programming of the pulse output by
overwriting the register values mentioned above.
This function permits use as a D/A converter with the addition of external circuits.
One-shot function: Detects the edge of trigger input, and permits single-pulse output. There is no
trigger input for PPG1.
This module consists of a 16-bit down-counter, a prescaler, a 16-bit synchronization setting register, a 16-bit
duty register, a 16-bit control register, one external trigger input pin, and one PPG output pin.
