<div class="textblock"><p>Initialize 12-bit ADC0 and/or ADC1. </p>
<p>ADC input, software trigger, 12-bit conversion<br />
The ADC allows two possible references: 2.5V or 3.3V.<br />
The internal 2.5V reference is lower noise, but limits the range to 0 to 2.5V.<br />
The other possibility is to use the analog voltage supply at 3.3V, making the ADC range 0 to 3.3V. In this driver, the 3.3V range is selected. There are several configurations (each with initialization and a read ADC with software trigger, busy-wait function)<br />

note to students****<br />
the data sheet says the ADC does not work when clock is 80 MHz however, the ADC seems to work on my boards at 80 MHz I suggest you try 80MHz, but if it doesn't work, switch to 40MHz </dd></dl>
