Deal with input ports output, helped article
I understand how to program a specific mode, but the question is what is each mode?
00 – analog input.
01 – the entrance is in the third state. (Set after reset).
10 – input with pull-up resistor
11 – reserved for future applications.
Analog input is the input which will be activated with different naprugi, for example for digitization in ADC?
The entrance is in the third state is high impedance state - ie the exit with wild resistance?
Input with pull-up resistor - this is the entrance which will be a logical level, right? but what is 1 or 0?
Reserved for future applications - then I do not really understand, but apparently if it is not worth it at all to use, and yet why?
00 – digital output
01 – digital output open drain
10 – digital output connected to specialized units
11 – digital output connected to specialized units with open drain
Digital output - with legs will be broadcast by a collection of zeros and ones corresponding to some letter?
Digital output open drain - what does it mean?
Digital output that is connected to the specialized units - what is this block? or as in the case reserved for future applications?
Digital output that is connected to specialized units with open drain - all fantasy was over.
Please correct my answers. In order to get data from the thermistor which mode is appropriate? what for the flashing led? Thank you!
