The M5211DEMO includes various input and output devices to aid application development. User I/O
devices include two momentary pushbutton switches, four green LEDs, and one potentiometer.
12.1
Two pushbutton switches provide momentary, active-low input, for user applications. Pull-ups internal to
the MCU must be enabled to provide error free switch operation. Pushbutton switches SW1 and SW2 are
connected to MCU I/O ports IRQ4* and IRQ7* respectively.
12.2
Indicators LED1 through LED4 are enabled by the LED_EN option header, shown in
LED is active-high and illuminates when a logic high signal is driven from the respective MCU I/O port.
A 3S buffer between the MCU port and the user LEDs provides the drive current necessary to control the
LEDs.
