3.2 GPIO Pins
The 25 GPIO pins of BGM111 module are organized into ports with up to 16 pins each. These GPIO pins can individually be configured
as either an output or input. More advanced configurations like open-drain, open-source, and glitch-filtering can be configured for each
individual GPIO pin. GPIO pins can also be overridden by peripheral pin connections like TIMER PWM outputs or USART communica-
tion, which can be routed to several locations on the device. The GPIO supports up to 16 asynchronous external pin interrupts, which
enable interrupts from any pin on the device. Also, the input value of a pin can be routed through the Peripheral Reflex System to other
peripherals. Except for a few special functions, the internal signal crossbar allows various peripheral functions to be assigned freely to
any GPIO pad, simplifying application board layout.
