PWM array controller
The STMPE16M31PX integrates 8 independent PWM controllers capable of blinking and
brightness control.
Each of the PWM controllers can be programmed to execute a series of blinking/brightness
control actions. One PWM controller could be mapped to more than one GPIO, allowing
multiple GPIO outputs to share a PWM controller.
Each PWM controller can be connected to any of GPIO channel through the routing network
which is controlled by GPIOn_PWM_CFG register (n = GPIO channel number).
