The ADC module can be configured to be used as a general digital test block which can generate 8 VDDA domain digital signals MCU_ADC[0-1]_DIG_TEST[0-7]. These digital outputs are made available to the device PinMux, where are used as general purpose digital inputs with some restrictions. The CTRLMMR_MCU_ADC[0-1]_CTRL[16] GPI_MODE_EN is the enable bit.
When GPI_MODE_EN bit is '0', the ADC is in normal operation.
When GPI_MODE_EN bit is '1', the ADC multiplexes the 8 analog inputs to 8 VDDA domain digital I/O block and outputs the signals to DIG_TEST[7-0] pins.
Restrictions on this usage are:
