Note: Pins 2 and 10 on the Aardvark are both connected to ground inside the Aardvark. As a result,
when the Aardvark is connected to the device board, it finds a reference ground at pin 10 and it takes
the RST~ line to ground on pin 2 at the same time. This means that once the Aardvark connection is
removed, the RST~ line is released and the 5000 Series chip resumes normal operation.
