USER OPTIONS
The M52210DEMO includes various input and output devices to aid application development.
User I/O devices include 2 pushbutton switches, 4 green LEDs, and 1 potentiometer. The ta-
ble below summarizes user option connections on the development board.
Table 2: User Option Connections
Pushbutton Switches
Two push button switches provide momentary, active-low input, for user applications. Pull-ups
internal to the MCU must be enabled to provide error-free switch operation.
switches SW1 and SW2 are connected to MCU I/O ports IRQ7* and IRQ1* respectively.
User LED’s
Four green LED’s are provided for use in application development and debug. Each LED is
configured for active-high operation. An LED_EN option header enables indicators LED1
through LED4. A 3S buffer between the MCU port and the user LED’s provides the drive cur-
rent necessary to control the LED’s.

In default configuration, this option header is not installed. Cut-
traces on the bottom of the PCB provide signal pathways. To iso-
late these analog inputs, simply open the cut-traces and install a
2x3, 0.1” pin header.
