Description
Output of PWM
By default, the PWM pin is configured to be active high: when the
PWM is configured to be fully on, the pin is driving high. When the
PWM is configured to be fully off, the pin is low. If firmware
requires the Blinking/Breathing PWM to be active low, the Polarity
bit in the GPIO Pin Control Register associated with the PWM can
be set to 1, which inverts the output polarity.
28.4 Host Interface
The blinking/breathing PWM block is accessed by a controller over the standard register interface.
28.5 Power, Clocks and Reset
This section defines the Power, Clock, and Reset parameters of the block.
