Test Modes
There is a user-available test mode that allows for loopback operation within the digital portion of
the ADC module. This can be useful for debugging software without having to provide actual analog
stimulus. This mode is available through the ADC Test Mode Loopback (ADCTMLB) register (see
page 318).
