7. 8-bit PPG Timer
This block is an 8-bit reload timer module for PPG output by controlling pulse output according to the timer
operation.
The hardware configuration of this block is an 8-bit down counter, two 8-bit reload registers, an 8-bit control
register, and an external pulse output pin. Using these components, the module provides the following features:
PPG output operation:
The module outputs pulse waves of any period and duty factor. It can also be used as
a D/A converter using an external circuit.
