The board operation is straightforward. Along with the TDBML interface
components required for proper operation of the MM912H634. Connectors provide access to all device pins and test points for
important signals.
JP13. Removing these jumpers allows low power mode current consumption to be demonstrated. JP6 supplies power to zener
diode D11.

The following list corresponds with the numbers listed on the picture.
The board is protected against reverse battery voltage by diode D10, which can withstand up to 3.0 A of continuous current.
There are fifteen jumpers on the board. Power to the LEDs is provided through jumpers JP4, JP8, JP10, JP11, JP12, and
Two push buttons are included: SW1 resets the MCU, and SW2 allows wake-up from one of the low power modes.
A small prototype area allows fast connection of additional components. Key power and ground vias are located around the
The EVM has three different grounds: LIN ground, main supply ground (also referred to as GND), and analog ground. All
