I am having this Microcontroller
In this Microcontroller, I am using the ADC peripheral and normal GPIO port.
On Page 58, table 42, There is a parameter called as Supply Current per ADC which is mentioned as 1mA. What does it mean? It also mentions that it depends on the conversion rate. Does it mean, if I connect a voltage (within the mentioned limits of the pin) with a series resistor to that ADC pin, that pin will consume 1mA? So, if I connect two ADC inputs to the ADC peripheral, it will consume 2mA?
Suppose, I configure a port as Input port. How much maximum current will the Microcontroller pin draw? Injection current will come only when I impress a voltage above that the supply voltage of the GPIO. And Leakage current, will come into picture only when the device is operating in low power state or shutdown. So, If I donot use the microcontroller in the above two conditions, (applying voltage to the pin within limits and in normal working mode), how much will the microcontroller pin take for a normal GPI input?
This Microcontroll has two supplies. ADC Reference supply high and ADC Reference supply low? Usually, I have seen only ADC reference supply as a single reference supply pin. But here, there is reference high and reference low? Any idea on why is this implemented and any use case of it?
